The light Sass library for managing your sizes and dimensions across breakpoints.

How to style modern applications in a simple way?

Installation

npm i sscss

Create your own _core.scss file with imports:

@import 'your-own-variables-and-settings';
@import '~sscss/sscss';

The file should be imported in all components where you will use Sass inheritances (@extend).

Settings

In the settings, you can use your own breakpoints in the px unit.
The interpolation key (boolean) in the map is optional and allows overwriting your global settings.

Example of breakpoints:

$mobile: 320px;
$tablet: 768px;
$desktop: 1024px;

Example of required settings:

$sscss-font-size: (
  'small':    ($mobile: 12px,  $tablet: 14px,  $desktop: 16px,  'interpolation': true),
  'medium':   ($mobile: 14px,  $tablet: 18px),
  'big':      ($mobile: 24px),
);

$sscss-dimension: (
  'small':    ($mobile: 4px,   $tablet: 8px,   $desktop: 16px,  'interpolation': true),
  'medium':   ($mobile: 8px,   $desktop: 32px),
  'big':      ($mobile: 16px,  $tablet: 32px,  'interpolation': false),
);

---

In the app you can use:

• the @extend approach allows you avoid styles generated outside your components.
• the .class approach allows you to generate small global utility classes.
• the linear interpolation or standard breakpoint behaviors.

Example of optional global settings:

$sscss-font-interpolation: false;
$sscss-font-as-class: false;

$sscss-dimension-interpolation: false;
$sscss-dimension-as-class: false;

Variable	Description	Default
$sscss-font-interpolation	Settings for linear interpolation.	false
$sscss-font-as-class	Settings for .class or @extend approach.	false
$sscss-dimension-interpolation	Settings for linear interpolation.	false
$sscss-dimension-as-class	Settings for .class or @extend approach.	false
