Autoprefixer

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):

1::placeholder {
2  color: gray;
3}
4
5.image {
6  background-image: url(image@1x.png);
7}
8@media (min-resolution: 2dppx) {
9  .image {
10    background-image: url(image@2x.png);
11  }
12}

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.

1::-moz-placeholder {
2  color: gray;
3}
4::placeholder {
5  color: gray;
6}
7
8.image {
9  background-image: url(image@1x.png);
10}
11@media (-webkit-min-device-pixel-ratio: 2),
12       (min-resolution: 2dppx) {
13  .image {
14    background-image: url(image@2x.png);
15  }
16}
