PostCSS Mixins

PostCSS plugin for mixins.

Note, that you must set this plugin before postcss-simple-vars
and postcss-nested.

 @define-mixin icon $network, $color: blue {
    .icon.is-$(network) {
        color: $color;
        @mixin-content;
    }
    .icon.is-$(network):hover {
        color: white;
        background: $color;
    }
}

@mixin icon twitter {
    background: url(twt.png);
}
@mixin icon youtube, red {
    background: url(youtube.png);
}

 .icon.is-twitter {
    color: blue;
    background: url(twt.png);
}
.icon.is-twitter:hover {
    color: white;
    background: blue;
}
.icon.is-youtube {
    color: red;
    background: url(youtube.png);
}
.icon.is-youtube:hover {
    color: white;
    background: red;
}

postcss-utilities collection is better for clearfix and other popular hacks.
For simple cases you can use postcss-define-property.
