PostCSS plugin to parse CSS and add vendor prefixes to CSS rules using values from Can I Use. It is recommended by Google and used in Twitter and Alibaba.

Write your CSS rules without vendor prefixes (in fact, forget about them entirely):

::placeholder {
  color: gray;
}

.image {
  background-image: url([email protected]);
}
@media (min-resolution: 2dppx) {
  .image {
    background-image: url([email protected]);
  }
}

Autoprefixer will use the data based on current browser popularity and property support to apply prefixes for you. You can try the interactive demo of Autoprefixer.

::-moz-placeholder {
  color: gray;
}
:-ms-input-placeholder {
  color: gray;
}
::placeholder {
  color: gray;
}

.image {
  background-image: url([email protected]);
}
@media (-webkit-min-device-pixel-ratio: 2),
       (min-resolution: 2dppx) {
  .image {
    background-image: url([email protected]);
  }
}
