Change an HTML5 input's placeholder color with CSS

Question

Chrome supports the placeholder attribute on input[type=text] elements (others probably do too).

But the following CSS doesn\'t do anything

Answer 1

For Sass users:

// Create placeholder mixin
@mixin placeholder($color, $size:"") {
  &::-webkit-input-placeholder {
    color: $color;
    @if $size != "" {
      font-size: $size;
    }
  }
  &:-moz-placeholder {
    color: $color;
    @if $size != "" {
      font-size: $size;
    }
  }
  &::-moz-placeholder {
    color: $color;
    @if $size != "" {
      font-size: $size;
    }
  }
  &:-ms-input-placeholder {
    color: $color;
    @if $size != "" {
      font-size: $size;
    }
  }
}

// Use placeholder mixin (the size parameter is optional)
[placeholder] {
  @include placeholder(red, 10px);
}
