    postcss-discard-unused

    Discard unused counter styles, keyframes and fonts.

    Install

    With npm do:

    npm install postcss-discard-unused --save
    

    Example

    This module will discard unused at rules in your CSS file, if it cannot find any selectors that make use of them. It works on @counter-style, @keyframes and @font-face.

    Input

    @counter-style custom {
        system: extends decimal;
        suffix: "> "
    }
    
    @counter-style custom2 {
        system: extends decimal;
        suffix: "| "
    }
    
    a {
        list-style: custom
    }

    Output

    @counter-style custom {
        system: extends decimal;
        suffix: "> "
    }
    
    a {
        list-style: custom
    }

    Note that this plugin is not responsible for normalising font families, as it makes the assumption that you will write your font names consistently, such that it considers these two declarations differently:

    h1 {
        font-family: "Helvetica Neue"
    }
    
    h2 {
        font-family: Helvetica Neue
    }

    However, you can mitigate this by including postcss-minify-font-values before this plugin, which will take care of normalising quotes, and deduplicating. For more examples, see the tests.

    Usage

    See the PostCSS documentation for examples for your environment.
