[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):
|
||
|
||
```css
|
||
::placeholder {
|
||
color: gray;
|
||
}
|
||
|
||
.image {
|
||
background-image: url(image@1x.png);
|
||
}
|
||
@media (min-resolution: 2dppx) {
|
||
.image {
|
||
background-image: url(image@2x.png);
|
||
}
|
||
}
|
||
```
|
||
|
||
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.
|
||
|
||
```css
|
||
::-moz-placeholder {
|
||
color: gray;
|
||
}
|
||
:-ms-input-placeholder {
|
||
color: gray;
|
||
}
|
||
::-ms-input-placeholder {
|
||
color: gray;
|
||
}
|
||
::placeholder {
|
||
color: gray;
|
||
}
|
||
|
||
.image {
|
||
background-image: url(image@1x.png);
|
||
}
|
||
@media (-webkit-min-device-pixel-ratio: 2),
|
||
(min-resolution: 2dppx) {
|
||
.image {
|
||
background-image: url(image@2x.png);
|
||
}
|
||
}
|

```
