About

Forget about vendor prefixes. Just write pure (S)CSS. This plugin adds vendor prefixes (depending on your settings) to CSS rules using values from Can I Use.

Write your CSS rules without vendor prefixes:

:fullscreen a {
    display: flex
}

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.

:-webkit-full-screen a {
    display: -webkit-box;
    display: flex
}
:-moz-full-screen a {
    display: flex
}
:-ms-fullscreen a {
    display: -ms-flexbox;
    display: flex
}
:fullscreen a {
    display: -webkit-box;
    display: -ms-flexbox;
    display: flex
}

Autoprefixer uses Browserslist, so you can specify the browsers you want to target in your project by queries like last 2 versions or > 5%.

See Browserslist docs for queries, browser names, config format, and default value.

Or visit the Autoprefixer project page for more informations.
