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

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

<pre><code>
::placeholder {
color: gray;
}

.image {
background-image: url(image@1x.png);
}
@media (min-resolution: 2dppx) {
.image {
background-image: url(image@2x.png);
}
}
</code></pre>

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

<pre><code>
::-moz-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);
}
}
</code></pre>
