sassy-lib v1.0.1

Sassy-lib

A minimalistic sass breakpoint library for your next project.

Installation

npm i sassy-lib

After installation, import the library in your .scss file.

@import './node_modules/sassy-lib/main.scss';

Absolute imports do not work. You need to import it manually.

Library defaults

Default breakpoints:

$breakpoints: (
  xs: 0,
  sm: 640px,
  md: 768px,
  lg: 1024px,
  xl: 1280px,
);

Default infix separator (more info at the bottom of the page):

$breakpoint-infix-separator: "-";

If you need to overwrite the values just define the breakpoint in your .scss file and import the library after declaring the breakpoint. Any overwrites must come before importing the library.

$breakpoints: (
  xs: 0,
  sm: 640px,
  md: 768px,
  lg: 1024px,
  xl: 1280px,
);

@import './node_modules/sassy-lib/main.scss';

// Note: The first value in the $breakpoints map should be 0.

Usage

The library provides a breakpoint mixin which accepts 3 args:

• breakpoint name, for example: sm, md, etc. This is same as your $breakpoints map key.
• direction, for example: up, down, only. Further explanation provided below.
• $breakpoints map. The default value is mention on the top of the page. Even if you need to overwrite the default value, consider creating a separate file for your breakpoints as mentioned above.

The library handles 3 directions, namely:

• up (min-width)
• down (max-width)
• only (min-width and max-width)

To use any of these directions (default is up), you need to include the breakpoint mixin.

@include breakpoint(sm) {
  // your styles
}
// Same as @media (min-width: 640px) {}

@include breakpoint(sm, down) {
  // your styles
}
// Same as @media (max-width: 639.98px) {}

@include breakpoint(sm, only) {
  // your styles
}
// Same as @media (min-width: 640px and max-width: 767.98px) {}

Creating utility classes

Sassy-lib also provides a powerful api called breakpoint-infix that you can use to create your utility classes.

$displays: (
  flex: flex,
  block: block,
);

// $breakpoints is your key-value pair of breakpoint map

@each $breakpoint in map-keys($breakpoints) {
  // provided by the library
  $bp-sort: breakpoint-infix($breakpoint);

  @include breakpoint($breakpoint) {
    @each $prop, $value in $displays {
      .#{$bp-sort}#{$prop} {
        display: $value;
      }
    }
  }
}

// creates
.flex {
  display: flex;
}

@media (min-width: 640px) {
  .sm-flex {
    display: flex;
  }
}

// etc
// Note: Please use the $bp-sort before your class.

The default infix separator is "-", but you can overwrite by overwriting the $breakpoint-infix-separator variable.

Tip

You can also create TailwindCSS like classes by overwriting the $breakpoint-infix-separator value to $breakpoint-infix-separator: "\\:", which will generate similar classes.
