{ kusass }

{ kusass } is a small library of sass mixins and functions that I use in small projects to help me deal with BEM and unit conversion.

The unit conversion functions have been stolen picked from Bourbon.

Installation

Install via Bower:

bower install kcmr/kusass

Or download it.

Usage

Import into your main scss:

@import "kusass/kusass";

Override $em-base var if you need it. The default font-size is 16px.

@import "kusass/kusass";
@import "myvars";

In _myvars.scss:

$em-base: 14px;

Available mixins

BEM helpers

elem

@include elem($block, 'classname')

This is useful when you need to apply styles to a BEM element inside a modifier or state class.

Example:

.my-block {
  $block: &;
  
  &--modifier {
    @include elem($block, 'element') {
      // styles for .my-block--modifier .my-block__element
    }
  }
  
  &.is-active {
    @include elem($block, 'element') {
      // styles for .my-block.is-active .my-block__element
    }
  }
}

mod

@include mod($block, 'classname')

I'm thinking if this mixin has any utility…

Available functions

Unit conversion

Check out the Bourbon docs about rem and em functions.

rem

Converts px to rems.

It asumes that default font-size is 16px. You can override the default value in your own vars file by setting the var $em-base.

.class { font-size: rem(12); }
// or...
.class { font-size: rem(12px); }

em

Converts px to ems.

.class { font-size: em(12); } 
// or...
.class { font-size: em(12px); }
// or...
.class { font-size: em(12, 18); } // uses the second value as relative unit.
