Как изменить цвет navbar bootstrap 5 - Исправление ошибок и поиск оптимальных решений проблем

How it works

Here’s what you need to know before getting started with the navbar:

Navbars require a wrapping .navbar with .navbar-expand{-sm|-md|-lg|-xl|-xxl} for responsive collapsing and color scheme classes.
Navbars and their contents are fluid by default. Change the container to limit their horizontal width in different ways.
Use our spacing and flex utility classes for controlling spacing and alignment within navbars.
Navbars are responsive by default, but you can easily modify them to change that. Responsive behavior depends on our Collapse JavaScript plugin.
Ensure accessibility by using a <nav> element or, if using a more generic element such as a <div>, add a role="navigation" to every navbar to explicitly identify it as a landmark region for users of assistive technologies.
Indicate the current item by using aria-current="page" for the current page or aria-current="true" for the current item in a set.

Supported content

Navbars come with built-in support for a handful of sub-components. Choose from the following as needed:

.navbar-brand for your company, product, or project name.
.navbar-nav for a full-height and lightweight navigation (including support for dropdowns).
.navbar-toggler for use with our collapse plugin and other navigation toggling behaviors.
Flex and spacing utilities for any form controls and actions.
.navbar-text for adding vertically centered strings of text.
.collapse.navbar-collapse for grouping and hiding navbar contents by a parent breakpoint.
Add an optional .navbar-scroll to set a max-height and scroll expanded navbar content.

Here’s an example of all the sub-components included in a responsive light-themed navbar that automatically collapses at the lg (large) breakpoint.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarSupportedContent">
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false">
            Dropdown
          </a>
          <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
            <li><a class="dropdown-item" href="#">Action</a></li>
            <li><a class="dropdown-item" href="#">Another action</a></li>
            <li><hr class="dropdown-divider"></li>
            <li><a class="dropdown-item" href="#">Something else here</a></li>
          </ul>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
        </li>
      </ul>
      <form class="d-flex">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-outline-success" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>

This example uses background (bg-light) and spacing (my-2, my-lg-0, me-sm-0, my-sm-0) utility classes.

Brand

The .navbar-brand can be applied to most elements, but an anchor works best, as some elements might require utility classes or custom styles.

Text

Add your text within an element with the .navbar-brand class.

<!-- As a link -->
<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
  </div>
</nav>

<!-- As a heading -->
<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <span class="navbar-brand mb-0 h1">Navbar</span>
  </div>
</nav>

Image

You can replace the text within the .navbar-brand with an <img>.

<nav class="navbar navbar-light bg-light">
  <div class="container">
    <a class="navbar-brand" href="#">
      <img src="/docs/5.0/assets/brand/bootstrap-logo.svg" alt="" width="30" height="24">
    </a>
  </div>
</nav>

Image and text

You can also make use of some additional utilities to add an image and text at the same time. Note the addition of .d-inline-block and .align-text-top on the <img>.

<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">
      <img src="/docs/5.0/assets/brand/bootstrap-logo.svg" alt="" width="30" height="24" class="d-inline-block align-text-top">
      Bootstrap
    </a>
  </div>
</nav>

Nav

Navbar navigation links build on our .nav options with their own modifier class and require the use of toggler classes for proper responsive styling. Navigation in navbars will also grow to occupy as much horizontal space as possible to keep your navbar contents securely aligned.

Add the .active class on .nav-link to indicate the current page.

Please note that you should also add the aria-current attribute on the active .nav-link.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNav">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
        </li>
      </ul>
    </div>
  </div>
</nav>

And because we use classes for our navs, you can avoid the list-based approach entirely if you like.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNavAltMarkup">
      <div class="navbar-nav">
        <a class="nav-link active" aria-current="page" href="#">Home</a>
        <a class="nav-link" href="#">Features</a>
        <a class="nav-link" href="#">Pricing</a>
        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
      </div>
    </div>
  </div>
</nav>

You can also use dropdowns in your navbar. Dropdown menus require a wrapping element for positioning, so be sure to use separate and nested elements for .nav-item and .nav-link as shown below.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNavDropdown">
      <ul class="navbar-nav">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-bs-toggle="dropdown" aria-expanded="false">
            Dropdown link
          </a>
          <ul class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
            <li><a class="dropdown-item" href="#">Action</a></li>
            <li><a class="dropdown-item" href="#">Another action</a></li>
            <li><a class="dropdown-item" href="#">Something else here</a></li>
          </ul>
        </li>
      </ul>
    </div>
  </div>
</nav>

Forms

Place various form controls and components within a navbar:

<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <form class="d-flex">
      <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
      <button class="btn btn-outline-success" type="submit">Search</button>
    </form>
  </div>
</nav>

Immediate child elements of .navbar use flex layout and will default to justify-content: space-between. Use additional flex utilities as needed to adjust this behavior.

<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand">Navbar</a>
    <form class="d-flex">
      <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
      <button class="btn btn-outline-success" type="submit">Search</button>
    </form>
  </div>
</nav>

Input groups work, too. If your navbar is an entire form, or mostly a form, you can use the <form> element as the container and save some HTML.

<nav class="navbar navbar-light bg-light">
  <form class="container-fluid">
    <div class="input-group">
      <span class="input-group-text" id="basic-addon1">@</span>
      <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
    </div>
  </form>
</nav>

Various buttons are supported as part of these navbar forms, too. This is also a great reminder that vertical alignment utilities can be used to align different sized elements.

<nav class="navbar navbar-light bg-light">
  <form class="container-fluid justify-content-start">
    <button class="btn btn-outline-success me-2" type="button">Main button</button>
    <button class="btn btn-sm btn-outline-secondary" type="button">Smaller button</button>
  </form>
</nav>

Text

Navbars may contain bits of text with the help of .navbar-text. This class adjusts vertical alignment and horizontal spacing for strings of text.

<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <span class="navbar-text">
      Navbar text with an inline element
    </span>
  </div>
</nav>

Mix and match with other components and utilities as needed.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar w/ text</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarText">
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
      </ul>
      <span class="navbar-text">
        Navbar text with an inline element
      </span>
    </div>
  </div>
</nav>

Color schemes

Theming the navbar has never been easier thanks to the combination of theming classes and background-color utilities. Choose from .navbar-light for use with light background colors, or .navbar-dark for dark background colors. Then, customize with .bg-* utilities.

<nav class="navbar navbar-dark bg-dark">
  <!-- Navbar content -->
</nav>

<nav class="navbar navbar-dark bg-primary">
  <!-- Navbar content -->
</nav>

<nav class="navbar navbar-light" style="background-color: #e3f2fd;">
  <!-- Navbar content -->
</nav>

Containers

Although it’s not required, you can wrap a navbar in a .container to center it on a page–though note that an inner container is still required. Or you can add a container inside the .navbar to only center the contents of a fixed or static top navbar.

<div class="container">
  <nav class="navbar navbar-expand-lg navbar-light bg-light">
    <div class="container-fluid">
      <a class="navbar-brand" href="#">Navbar</a>
    </div>
  </nav>
</div>

Use any of the responsive containers to change how wide the content in your navbar is presented.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-md">
    <a class="navbar-brand" href="#">Navbar</a>
  </div>
</nav>

Placement

Use our position utilities to place navbars in non-static positions. Choose from fixed to the top, fixed to the bottom, or stickied to the top (scrolls with the page until it reaches the top, then stays there). Fixed navbars use position: fixed, meaning they’re pulled from the normal flow of the DOM and may require custom CSS (e.g., padding-top on the <body>) to prevent overlap with other elements.

Also note that .sticky-top uses position: sticky, which isn’t fully supported in every browser.

<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Default</a>
  </div>
</nav>

<nav class="navbar fixed-top navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Fixed top</a>
  </div>
</nav>

<nav class="navbar fixed-bottom navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Fixed bottom</a>
  </div>
</nav>

<nav class="navbar sticky-top navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Sticky top</a>
  </div>
</nav>

Add .navbar-nav-scroll to a .navbar-nav (or other navbar sub-component) to enable vertical scrolling within the toggleable contents of a collapsed navbar. By default, scrolling kicks in at 75vh (or 75% of the viewport height), but you can override that with the local CSS custom property --bs-navbar-height or custom styles. At larger viewports when the navbar is expanded, content will appear as it does in a default navbar.

Please note that this behavior comes with a potential drawback of overflow—when setting overflow-y: auto (required to scroll the content here), overflow-x is the equivalent of auto, which will crop some horizontal content.

Here’s an example navbar using .navbar-nav-scroll with style="--bs-scroll-height: 100px;", with some extra margin utilities for optimum spacing.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar scroll</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarScroll" aria-controls="navbarScroll" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarScroll">
      <ul class="navbar-nav me-auto my-2 my-lg-0 navbar-nav-scroll" style="--bs-scroll-height: 100px;">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="#" id="navbarScrollingDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false">
            Link
          </a>
          <ul class="dropdown-menu" aria-labelledby="navbarScrollingDropdown">
            <li><a class="dropdown-item" href="#">Action</a></li>
            <li><a class="dropdown-item" href="#">Another action</a></li>
            <li><hr class="dropdown-divider"></li>
            <li><a class="dropdown-item" href="#">Something else here</a></li>
          </ul>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Link</a>
        </li>
      </ul>
      <form class="d-flex">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-outline-success" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>

Responsive behaviors

Navbars can use .navbar-toggler, .navbar-collapse, and .navbar-expand{-sm|-md|-lg|-xl|-xxl} classes to determine when their content collapses behind a button. In combination with other utilities, you can easily choose when to show or hide particular elements.

For navbars that never collapse, add the .navbar-expand class on the navbar. For navbars that always collapse, don’t add any .navbar-expand class.

Toggler

Navbar togglers are left-aligned by default, but should they follow a sibling element like a .navbar-brand, they’ll automatically be aligned to the far right. Reversing your markup will reverse the placement of the toggler. Below are examples of different toggle styles.

With no .navbar-brand shown at the smallest breakpoint:

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarTogglerDemo01">
      <a class="navbar-brand" href="#">Hidden brand</a>
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
        </li>
      </ul>
      <form class="d-flex">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-outline-success" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>

With a brand name shown on the left and toggler on the right:

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarTogglerDemo02" aria-controls="navbarTogglerDemo02" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarTogglerDemo02">
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
        </li>
      </ul>
      <form class="d-flex">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-outline-success" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>

With a toggler on the left and brand name on the right:

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarTogglerDemo03" aria-controls="navbarTogglerDemo03" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <a class="navbar-brand" href="#">Navbar</a>
    <div class="collapse navbar-collapse" id="navbarTogglerDemo03">
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
        </li>
      </ul>
      <form class="d-flex">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-outline-success" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>

External content

Sometimes you want to use the collapse plugin to trigger a container element for content that structurally sits outside of the .navbar . Because our plugin works on the id and data-bs-target matching, that’s easily done!

Collapsed content

Toggleable via the navbar brand.

<div class="collapse" id="navbarToggleExternalContent">
  <div class="bg-dark p-4">
    <h5 class="text-white h4">Collapsed content</h5>
    <span class="text-muted">Toggleable via the navbar brand.</span>
  </div>
</div>
<nav class="navbar navbar-dark bg-dark">
  <div class="container-fluid">
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
  </div>
</nav>

When you do this, we recommend including additional JavaScript to move the focus programmatically to the container when it is opened. Otherwise, keyboard users and users of assistive technologies will likely have a hard time finding the newly revealed content — particularly if the container that was opened comes before the toggler in the document’s structure. We also recommend making sure that the toggler has the aria-controls attribute, pointing to the id of the content container. In theory, this allows assistive technology users to jump directly from the toggler to the container it controls–but support for this is currently quite patchy.

Loop

Responsive navbar expand/collapse classes (e.g., .navbar-expand-lg) are combined with the $breakpoints map and generated through a loop in scss/_navbar.scss.

// Generate series of `.navbar-expand-*` responsive classes for configuring
// where your navbar collapses.
.navbar-expand {
  @each $breakpoint in map-keys($grid-breakpoints) {
    $next: breakpoint-next($breakpoint, $grid-breakpoints);
    $infix: breakpoint-infix($next, $grid-breakpoints);

    // stylelint-disable-next-line scss/selector-no-union-class-name
    &#{$infix} {
      @include media-breakpoint-up($next) {
        flex-wrap: nowrap;
        justify-content: flex-start;

        .navbar-nav {
          flex-direction: row;

          .dropdown-menu {
            position: absolute;
          }

          .nav-link {
            padding-right: $navbar-nav-link-padding-x;
            padding-left: $navbar-nav-link-padding-x;
          }
        }

        .navbar-nav-scroll {
          overflow: visible;
        }

        .navbar-collapse {
          display: flex !important; // stylelint-disable-line declaration-no-important
          flex-basis: auto;
        }

        .navbar-toggler {
          display: none;

      }
    }
  }

Just add an id to the HTML navbar, such as:

<nav id="navbar-yellow" class="navbar navbar-default navbar-fixed-top" role="navigation">

With this id you can style the navbar color, but also the links and dropdowns

Black

Yellow

The navigation bar color can be changed in Bootstrap using 2 methods:
Method 1: Using the inbuilt color classes
Changing the text color
The text color of the navigation bar can be changed using two inbuilt classes:

navbar-light: This class will set the color of the text to dark. This is used when using a light background color.
navbar-dark: This class will set the color of the text to light. This is used when using a dark background color.

Changing the background color:
Bootstrap 4 has a few inbuilt classes for the colors of any background. These can be used to set the color of the background of the navigation bar. The various background classes available are:

.bg-primary: This sets the color to the primary color.
.bg-secondary: This sets the color to the secondary color.
.bg-success: This sets the color to the success color.
.bg-danger: This sets the color to the danger color.
.bg-warning: This sets the color to the warning color.
.bg-info: This sets the color to the info color.
.bg-light: This sets the color to the light color.
.bg-dark: This sets the color to the dark color.
.bg-white: This sets the color to the white color.
.bg-transparent: This sets the navbar to be transparent.

Method 2: Creating a custom class for the navigation bar
A custom class can be created to specify the background color and the text color of the navbar. This class is styled using CSS according to the required values. The names of the classes are kept in a manner to override the inbuilt navigation bar classes.
The background color is set by directly specifying the background-color property with the color needed.

html

/* Modify the background color */

.navbar-custom {

background-color: lightgreen;

}

The navbar text and the brand text color can be set using the .navbar-text and .navbar-brand classes. These are the inbuilt navigation bar classes that are be overridden by using the same class name. The text color is specified using the color property.

html

/* Modify brand and text color */

.navbar-custom .navbar-brand,

.navbar-custom .navbar-text {

color: green;

Bootstrap 5 Navbar component

Documentation and examples for powerful, responsive navigation header — MDB navbar.
Includes support for branding, navigation, and more, including support for our collapse
plugin.

Video tutorial

Basic example

A basic example of the navbar with the most common elements like link, search form, brand, and
dropdown. All of them are explained in detail in the
supported content section.

Note: this example uses
color
(bg-light) and
spacing
(my-2, my-lg-0, me-sm-0, my-sm-0) utility
classes.

How it works

Here’s what you need to know before getting started with the navbar:

Navbars require a wrapping .navbar with
.navbar-expand{-sm|-md|-lg|-xl|-xxl} for responsive collapsing and
color scheme classes.
Navbars and their contents are fluid by default. Change the
container to limit their horizontal width in different
ways.
Use our
spacing and
flex utility classes for controlling spacing
and alignment within navbars.
Navbars are responsive by default, but you can easily modify them to change that. Responsive
behavior depends on our Collapse JavaScript plugin.
Ensure accessibility by using a
<nav> element or, if using a more generic element such as a
<div>, add a role="navigation" to every navbar to explicitly
identify it as a landmark region for users of assistive technologies.
Indicate the current item by using
aria-current="page" for the current page or
aria-current="true" for the current item in a set.

Supported content

Navbars come with built-in support for a handful of sub-components. Choose from the following
as needed:

.navbar-brand for your company, product, or project name.
.navbar-nav for a full-height and lightweight navigation (including support for
dropdowns).
.navbar-toggler for use with our collapse plugin and other
navigation toggling
behaviors.
Flex and spacing utilities for any form controls and actions.
.navbar-text for adding vertically centered strings of text.
.collapse.navbar-collapse for grouping and hiding navbar contents by a parent
breakpoint.

Apart from listed above, navbar supports also components like breadcrumbs, forms, buttons,
icons, flags, avatars, badges, and a few more.

Brand

The .navbar-brand can be applied to most elements, but an anchor works best, as
some elements might require utility classes or custom styles.

Adding images to the .navbar-brand will likely always require custom styles or
utilities to properly size. Here are some examples to demonstrate.

Nav

Navbar navigation links build on our
.nav options with their own modifier class and require the use of
toggler classes for proper responsive styling.
Navigation in navbars will also grow to occupy as much horizontal space as
possible
to keep your navbar contents securely aligned.

Active states—with .active—to indicate the current page can be applied directly
to .nav-links or their immediate parent .nav-items.

Please note that you should also add the
aria-current attribute on the .nav-link itself.

And because we use classes for our navs, you can avoid the list-based approach entirely if
you like.

Forms

Place various form controls and components within a navbar:

Immediate child elements of .navbar use flex layout and will default to
justify-content: space-between. Use additional
flex utilities
as needed to adjust this behavior.

White form for dark theme.

Buttons

Various buttons are supported as part of these navbar forms, too. This is also a great
reminder that vertical alignment utilities can be used to align different sized elements.

Text

Navbars may contain bits of text with the help of
.navbar-text. This class adjusts vertical alignment and horizontal spacing for
strings of text.

Mix and match with other components and utilities as needed.

Dropdown

You can also use dropdowns in your navbar nav. Dropdown menus require a wrapping element for
positioning, so be sure to use separate and nested elements for
.nav-item and .nav-link as shown below.

Learn more about dropdowns in our
dropdown docs.

Breadcrumb

Very common use case — breadcrumb in the navbar.

Icons

Choose from hundreds of our
icons and simply add them to the navbar.

Note: We add .d-flex .flex-row classes to keep the icons
inline when the navbar is collapsed. Without this, they will stack one under another.

Badges

Badges can be very useful for presenting
counters, for example in the shopping cart.

Notifications

You can mix icon with dropdown and create a notification dropdown to indicate important news
for visitors. Add
.hidden-arrow class to hide a dropdown arrow.

Flags

Use dropdown together with
flags to create a language switch.

Avatar

By combining simple image and dropdown you can create an avatar with typical user options.

Content alignment

To align navbar content to the right or left use
me-auto or ms-auto classes. For content centering use
flexbox
utilities.

Left aligned

Add .me-auto class next to the .navbar-nav to align the content to
the left.

Right aligned

Add .ms-auto class next to the .navbar-nav to align the content to
the right.

Centered

Remove .ms-auto or .me-auto class and add
.justify-content-center next to the .navbar-collapse to center the
content.

Colors

Sample colors

Theming the navbar has never been easier thanks to the combination of theming classes and
background-color utilities. Choose from .navbar-light for use with
light background colors, or .navbar-dark for dark background colors. Then,
customize with .bg-* utilities.

See also our
color docs
to learn more about colors.

Secondary icons

The secondary icons on a white background give a light, soft look. They are also helpful in keeping the navbar and sidenav appear consistent as they are the same color as the icons in sidenav.

Add .link-secondary class to the link to change the color.

Containers

Although it’s not required, you can wrap a navbar in a
.container to center it on a page–though note that an inner container is still
required. Or you can add a container inside the .navbar to only center the
contents of a fixed or static top navbar.

Use any of the responsive containers to change how wide the content in your navbar is
presented.

Placement

Use our
position utilities
to place navbars in non-static positions. Choose from fixed to the top, fixed to the bottom,
or stickied to the top (scrolls with the page until it reaches the top, then stays there).
Fixed navbars use position: fixed, meaning they’re pulled from the normal flow of
the DOM and may require custom CSS (e.g., padding-top on the
<body>) to prevent overlap with other elements.

Also note that
.sticky-top uses position: sticky, which
isn’t fully supported in every browser.

Responsive behaviors

Navbars can use .navbar-toggler, .navbar-collapse, and
.navbar-expand{-sm|-md|-lg|-xl|-xxl} classes to determine when their content
collapses behind a button. In combination with other utilities, you can easily choose when to
show or hide particular elements.

For navbars that never collapse, add the
.navbar-expand class on the navbar. For navbars that always collapse, don’t add
any .navbar-expand class.

Toggler

Navbar togglers are left-aligned by default, but should they follow a sibling element like a
.navbar-brand, they’ll automatically be aligned to the far right. Reversing
your markup will reverse the placement of the toggler. Below are examples of different
toggle styles.

With no .navbar-brand shown at the smallest breakpoint:

With a brand name shown on the left and toggler on the right:

With a toggler on the left and brand name on the right:

External content

Sometimes you want to use the collapse plugin to trigger a container element for content
that structurally sits outside of the
.navbar. Because our plugin works on the id and
data-mdb-target matching, that’s easily done!

Collapsed content

Toggleable via the navbar brand.

Advanced examples

Advanced examples of navbars usage.

Facebook style

A typical example of Facebook navbar usage — 3 columns with icons and distinctive
notifications plus a search field on the left.

Bootstrap 5 Navbars

A navigation bar is a navigation header that is placed at the top of the
page:

Basic Navbar

With Bootstrap, a navigation bar can extend or collapse, depending on the
screen size.

A standard navigation bar is created with the .navbar
class, followed by a responsive collapsing class: .navbar-expand-xxl|xl|lg|md|sm
(stacks the navbar vertically on xxlarge, extra large, large, medium or small screens).

To add links inside the navbar, use either an <ul> element
(or a <div>) with class="navbar-nav".
Then add <li> elements with a .nav-item class
followed by an <a> element with a .nav-link class:

Example

<!— A grey horizontal navbar that becomes
vertical on small screens —>
<nav class=»navbar navbar-expand-sm
bg-light»>

</nav>

Try it Yourself »

<!— Blue
background with white text —>
<nav class=»navbar navbar-expand-sm
bg-primary navbar-dark»>…</nav>

Try it Yourself »

Active/disabled state: Add the .active class to an
<a> element to highlight the current link, or the .disabled class to indicate that the link is un-clickable.

Brand / Logo

The .navbar-brand class is used to highlight the brand/logo/project name of your page:

Example

Try it Yourself »

When using the .navbar-brand class with images, Bootstrap
5 will automatically style the image to fit the navbar vertically.

Example

Example

Try it Yourself »

Use the .fixed-bottom class to make the navbar stay at
the bottom of the page:

Example

Try it Yourself »

Use the .sticky-top class to make the navbar fixed/stay at
the top of the page when you scroll past it. Note:
This class does not work in IE11 and earlier (will treat it as position:relative).

Add a fully-functional, responsive navbar to your website with minimal code.

The Bootstrap 5 navbar is a simple wrapper for positioning branding, navigation, and other elements into a navigation header.

Basic Navbar

Here’s an explanation:

Wrap everything inside a nav element with the .navbar class and a .navbar-expand{-sm|-md|-lg|-xl|-xxl} class, along with a color scheme.
For the togglable menu on smaller devices, use a button element with .navbar-toggler. To display the «hamburger», use the .navbar-toggler-icon class on a span element.
For a list of links, use a ul with the .navbar-nav class.
For each individual list item, use li with .nav-item.
For the individual links use a with .nav-link.

Navbars with Dropdowns

You can add dropdown menus to your navbar. Just add the dropdown code to a li element with the .dropdown class applied.

Current Page

Use the .active class to mark a link as the current page or section (apply it to the li).

Also add a span with .sr-only to communicate this to screen readers.

Alignment

You can use any of the spacing utilities (such as me-auto) or any of the flexbox alignment utilities (such as .justify-content-end) to align elements within the navbar.

The flexbox classes take their names from the actual flexbox property/value declaration. This makes it easy to guess the name of the most appropriate class for a given situation.

You can also add a responsive abbreviation to effect an alignment only on certain viewport sizes. For example, .justify-content-lg-end applies justify-content: end on large devices and up.

Colors

Bootstrap provides various options for adding color to navbars. The way it works is, you specify light or dark (via .navbar-light or .navbar-dark), then specify a color. Color can be specified either via one of Bootstrap’s color classes (eg, .bg-primary, .bg-dark), or by specifying your own color with CSS (eg, using background-color).

The previous examples already specify the navbar color. Here are some more examples.

Primary Color, Light

Here, we use .bg-primary along with .navbar-light:

Primary Color, Dark

Here, we use .bg-primary along with .navbar-dark:

Custom Color

To specify your own custom color, omit any .bg-* class (eg, remove .bg-primary) and add your own color using CSS.

Fixed Navbars

You can fix a navbar to the top or bottom of the viewport by using either .fixed-top or .fixed-bottom.

Fixed Top

Fixed Bottom

Padding Required

When using fixed navbars, you will usually need to add padding to compensate for the height of the navbar (otherwise the navbar will hide your content).

For example, for a «fixed top» navbar, try this:

And for «fixed bottom»:

You can adjust these values as required.

Bootstrap 5 is in alpha when this is written and it’s subject to change.

Bootstrap is a popular UI library for any JavaScript apps.

In this article, we’ll look at how to customize navbars with Bootstrap 5.

Text

We can add text to our navbars.

For example, we can write:

<nav class="navbar navbar-light bg-light">  
  <div class="container-fluid">  
    <span class="navbar-text">  
      Lorem ipsum dolor sit amet, consectetur adipiscing elit.  
    </span>  
  </div>  
</nav>

to add the text.

We add the navbar-text class to style the text to fit the navbar.

Also, we can mix and match other utility classes as we wish:

<nav class="navbar navbar-expand-lg navbar-light bg-light">  
  <div class="container-fluid">  
    <a class="navbar-brand" href="#">App</a>  
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">  
      <span class="navbar-toggler-icon"></span>  
    </button>  
    <div class="collapse navbar-collapse" id="navbarText">  
      <ul class="navbar-nav mr-auto mb-2 mb-lg-0">  
        <li class="nav-item">  
          <a class="nav-link active" href="#">Home</a>  
        </li>  
        <li class="nav-item">  
          <a class="nav-link" href="#">Profile</a>  
        </li>  
        <li class="nav-item">  
          <a class="nav-link" href="#">Settings</a>  
        </li>  
      </ul>  
      <span class="navbar-text">  
        more text  
      </span>  
    </div>  
  </div>  
</nav>

We have a navbar with a brand and nav item.

We add the mr-auto to add right margin to our nav.

And we have the mb-2 and mb-lg-0 classes to change the bottom margin depending on the width of the screen.

If it’s large, then there’s no bottom margin.

Color Schemes

The color schemes of navbar can also change.

We can add the navbar-dark and bg-dark classes to make the navbar dark.

navbar-dark and bg-primary classes make the navbar blue.

We can also apply our own styles.

For example, we can write:

<nav class="navbar navbar-dark bg-dark">  
  <div class="container-fluid">  
    <a class="navbar-brand" href="#">App</a>  
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">  
      <span class="navbar-toggler-icon"></span>  
    </button>  
    <div class="collapse navbar-collapse" id="navbarText">  
      <ul class="navbar-nav mr-auto mb-2 mb-lg-0">  
        <li class="nav-item">  
          <a class="nav-link active" href="#">Home</a>  
        </li>  
        <li class="nav-item">  
          <a class="nav-link" href="#">Profile</a>  
        </li>  
        <li class="nav-item">  
          <a class="nav-link" href="#">Settings</a>  
        </li>  
      </ul>  
    </div>  
  </div>  
</nav>

to add a dark navbar.

The classes are applied to the root navbar element.

We can also apply our own navbar color:

<nav class="navbar navbar-light" style="background-color: lightblue">  
  <div class="container-fluid">  
    <a class="navbar-brand" href="#">App</a>  
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">  
      <span class="navbar-toggler-icon"></span>  
    </button>  
    <div class="collapse navbar-collapse" id="navbarText">  
      <ul class="navbar-nav mr-auto mb-2 mb-lg-0">  
        <li class="nav-item">  
          <a class="nav-link active" href="#">Home</a>  
        </li>  
        <li class="nav-item">  
          <a class="nav-link" href="#">Profile</a>  
        </li>  
        <li class="nav-item">  
          <a class="nav-link" href="#">Settings</a>  
        </li>  
      </ul>  
    </div>  
  </div>  
</nav>

We added the style attribute to do that.

Containers

We can add a container class to center the nav bar on the page.

For example, we can write:

<div class="container">  
  <nav class="navbar navbar-expand-lg navbar-light bg-light">  
    <div class="container-fluid">  
      <a class="navbar-brand" href="#">App</a>  
    </div>  
  </nav>  
</div>

Then we’ll get some margins around the page.

Also, we can use any responsive containers to change the width of the navbar:

<nav class="navbar navbar-expand-lg navbar-light bg-light">  
  <div class="container-md">  
    <a class="navbar-brand" href="#">App</a>  
  </div>  
</nav>

We added the navbar-expand-lg class to make it expand when the screen hits the lg breakpoint or wider.

Placement

The placement of the navbar can also be changed.

For example, we can write:

<nav class="navbar fixed-top navbar-light bg-light">  
  <div class="container-fluid">  
    <a class="navbar-brand" href="#">Fixed Navbar</a>  
  </div>  
</nav>

Then we have the fixed-top class to make the navbar stick to the top.

To keep the navbar at the bottom of the screen, we can write:

<nav class="navbar fixed-bottom navbar-light bg-light">  
  <div class="container-fluid">  
    <a class="navbar-brand" href="#">Fixed Navbar</a>  
  </div>  
</nav>

The fixed-bottom class keeps the navbar at the bottom.

We can also use the sticky-top class to make it stick to the top:

<nav class="navbar sticky-top navbar-light bg-light">  
  <div class="container-fluid">  
    <a class="navbar-brand" href="#">Fixed Navbar</a>  
  </div>  
</nav>

Conclusion

We can place our navbar and its content the way we want with various classes.
