Как изменить цвет placeholder html

Implementation

There are three different implementations: pseudo-elements, pseudo-classes, and nothing.

• WebKit, Blink (Safari, Google Chrome, Opera 15+) and Microsoft Edge are using a pseudo-element: ::-webkit-input-placeholder. ^[Ref]
• Mozilla Firefox 4 to 18 is using a pseudo-class: :-moz-placeholder (one colon). ^[Ref]
• Mozilla Firefox 19+ is using a pseudo-element: ::-moz-placeholder, but the old selector will still work for a while. ^[Ref]
• Internet Explorer 10 and 11 are using a pseudo-class: :-ms-input-placeholder. ^[Ref]
• April 2017: Most modern browsers support the simple pseudo-element ::placeholder ^[Ref]

Internet Explorer 9 and lower does not support the placeholder attribute at all, while Opera 12 and lower do not support any CSS selector for placeholders.

The discussion about the best implementation is still going on. Note the pseudo-elements act like real elements in the Shadow DOM. A padding on an input will not get the same background color as the pseudo-element.

CSS selectors

User agents are required to ignore a rule with an unknown selector. See Selectors Level 3:

a group of selectors containing an invalid selector is invalid.

So we need separate rules for each browser. Otherwise the whole group would be ignored by all browsers.

::-webkit-input-placeholder { /* WebKit, Blink, Edge */
    color:    #909;
}
:-moz-placeholder { /* Mozilla Firefox 4 to 18 */
   color:    #909;
   opacity:  1;
}
::-moz-placeholder { /* Mozilla Firefox 19+ */
   color:    #909;
   opacity:  1;
}
:-ms-input-placeholder { /* Internet Explorer 10-11 */
   color:    #909;
}
::-ms-input-placeholder { /* Microsoft Edge */
   color:    #909;
}

::placeholder { /* Most modern browsers support this now. */
   color:    #909;
}

<input placeholder="Stack Snippets are awesome!">

Usage notes

• Be careful to avoid bad contrasts. Firefox’s placeholder appears to be defaulting with a reduced opacity, so needs to use opacity: 1 here.
• Note that placeholder text is just cut off if it doesn’t fit – size your input elements in em and test them with big minimum font size settings. Don’t forget translations: some languages need more room for the same word.
• Browsers with HTML support for placeholder but without CSS support for that (like Opera) should be tested too.
• Placeholders are no replacement for labels, so make sure you have a label, too
• Some browsers use additional default CSS for some input types (email, search). These might affect the rendering in unexpected ways. Use the properties -webkit-appearance and -moz-appearance to change that. Example:

    [type="search"] {
        -moz-appearance:    textfield;
        -webkit-appearance: textfield;
        appearance: textfield;
    }

/* do not group these rules */
*::-webkit-input-placeholder {
    color: red;
}
*:-moz-placeholder {
    /* FF 4-18 */
    color: red;
    opacity: 1;
}
*::-moz-placeholder {
    /* FF 19+ */
    color: red;
    opacity: 1;
}
*:-ms-input-placeholder {
    /* IE 10+ */
    color: red;
}
*::-ms-input-placeholder {
    /* Microsoft Edge */
    color: red;
}
*::placeholder {
    /* modern browser */
    color: red;
}

<input placeholder="hello"/> <br />
<textarea placeholder="hello"></textarea>

input::-webkit-input-placeholder,
textarea::-webkit-input-placeholder {
  color: #FF9900;
}

input:-moz-placeholder,
textarea:-moz-placeholder {
  color: #FF9900;
}

<textarea rows="4" cols="50" placeholder="Stack Snippets are nice!">
</textarea>

For Bootstrap and Less users, there is a mixin .placeholder:

// Placeholder text
// -------------------------
.placeholder(@color: @placeholderText) {
  &:-moz-placeholder {
    color: @color;
  }
  &:-ms-input-placeholder {
    color: @color;
  }
  &::-webkit-input-placeholder {
    color: @color;
  }
}

This will work fine. DEMO HERE:

input::-webkit-input-placeholder,
textarea::-webkit-input-placeholder {
  color: #666;
}
input:-moz-placeholder,
textarea:-moz-placeholder {
  color: #666;
}
input::-moz-placeholder,
textarea::-moz-placeholder {
  color: #666;
}
input:-ms-input-placeholder,
textarea:-ms-input-placeholder {
  color: #666;
}

<input type="text" placeholder="Value" />

In Firefox and Internet Explorer, the normal input text color overrides the color property of placeholders. So, we need to

::-webkit-input-placeholder { 
    color: red; text-overflow: ellipsis; 
}
:-moz-placeholder { 
    color: #acacac !important; text-overflow: ellipsis; 
}
::-moz-placeholder { 
    color: #acacac !important; text-overflow: ellipsis; 
} /* For the future */
:-ms-input-placeholder { 
    color: #acacac !important; text-overflow: ellipsis; 
}

I don’t remember where I’ve found this code snippet on the Internet (it wasn’t written by me, don’t remember where I’ve found it, nor who wrote it).

$('[placeholder]').focus(function() {
        var input = $(this);
        if (input.val() == input.attr('placeholder')) {
            input.val('');
            input.removeClass('placeholder');
        }
    }).blur(function() {
        var input = $(this);
        if (input.val() == '' || input.val() == input.attr('placeholder')) {
            input.addClass('placeholder');
            input.val(input.attr('placeholder'));
        }
    }).blur();
    $('[placeholder]').parents('form').submit(function() {
        $(this).find('[placeholder]').each(function() {
            var input = $(this);
            if (input.val() == input.attr('placeholder')) {
                input.val('');
            }
        })
    });

Just load this JavaScript code and then edit your placeholder with CSS by calling this rule:

form .placeholder {
   color: #222;
   font-size: 25px;
   /* etc. */
}

I think this code will work because a placeholder is needed only for input type text. So this one line CSS will be enough for your need:

input[type="text"]::-webkit-input-placeholder {
    color: red;
}

How about this

<input type="text" value="placeholder text" onfocus="this.style.color='#000'; 
    this.value='';" style="color: #f00;" />

No CSS or placeholder, but you get the same functionality.

input {
  filter: sepia(100%) saturate(400%) grayscale(0) contrast(200%) hue-rotate(68deg) invert(18%);
}

<input placeholder="Hello world!" />
<input type="date" /><br>
<input type="range" />
<input type="color" />

function stylElem() {
  stylo.dataset.hue = ((parseInt(stylo.value.substring(1), 16))/46666).toFixed(0)
  Array.from(document.querySelectorAll('input, audio, video')).forEach(function(e){
      e.style.cssText += ";filter:sepia(100%) saturate(400%)grayscale(0)contrast(200%)hue-rotate("+ stylo.dataset.hue+"deg)invert("+(stylo.dataset.hue/3.6)+"%)"
  out.innerText = e.style.cssText
})()}

stylElem()

body {background: black; color: white}

Choose a color!
<input type="color" id="stylo" oninput="stylElem()">
<br>
<div id="out"></div> <p>
  <input placeholder="Hello world!" />
  <input type="date" /><br>
  <input type="range" />
 <br>
<audio controls src="#"></audio> <br><br> 
<video controls src="#"></video>

For giving placeholder a color just use these lines of code:

::-webkit-input-placeholder { color: red; }
::-moz-placeholder {color: red; }
:-ms-input-placeholder { color: red; } 
:-o-input-placeholder { color: red; } 

Try this

input::-webkit-input-placeholder { /* WebKit browsers */
    color:    #f51;
}
input:-moz-placeholder { /* Mozilla Firefox 4 to 18 */
    color:    #f51;
}
input::-moz-placeholder { /* Mozilla Firefox 19+ */
    color:    #f51;
}
input:-ms-input-placeholder { /* Internet Explorer 10+ */
    color:    #f51;
}

<input type="text" placeholder="Value" />

For Firefox use:

 input:-moz-placeholder { color: #aaa; }
 textarea:-moz-placeholder { color: #aaa;}

For all other browsers (Chrome, IE, Safari), just use:

 .placeholder { color: #aaa; }
