PostCSS plugin that enables @if statements in your CSS
npm install postcss-conditionals-renewed@if` statements in your CSS.
Installation
`js
npm install postcss postcss-conditionals-renewed
`
Usage
`js
var fs = require('fs');
var postcss = require('postcss');
var conditionals = require('postcss-conditionals-renewed');
var css = fs.readFileSync('input.css', 'utf8');
var output = postcss()
.use(conditionals)
.process(css)
.css;
`
Using this `input.css`:
`css
.foo {
@if 3 < 5 {
background: green;
}
@else {
background: blue;
}
}
`
you will get:
`css
.foo {
background: green;
}
`

} @else if $type == monster {
color: green;
} @else {
