Bolts

v1.0.0

Bolts is a collection of practical Sass mixins and JS functions helping you deal with all the mundane website building and styling tasks, so that you can focus on creating something new. It aims to be a toolkit that does the things you're tired of.

Bolts does not output any unnessecary styles and all functions can be loaded separately through ES6 imports, making its footprint as tiny as possible.

  <div class="item is-small"></div>
</div>

SCSS

.items {
  @include inline-layout;

  .item {
    @media ( width-to(medium) ) {
      &.is-small { width: 50%; }
      &.is-medium, &.is-large { width: 100%; }
    }

    @media ( width-from(medium) ) {
      &.is-small  { width: 25%; }

Usage:

.menu.is-open {

  .menu-item {
    transform: translateX(-50px);
    transition: transform 300ms ease;

    @include stagger-delay(

      $iterations: 10
    );
  }
}

Arguments:

$type	transition, animation	transition	Specifies if the mixin outputs transition-delayor animation-delay.
$start	CSS time unit	0s	Add a delay before the incremantal-delay starts.
$increment	CSS time unit	0s	The amount of time incremented for each item.
$iterations	Number	0	Amount of iterations to output. This is needed since Sass doesn't have access to the DOM.

$direction	forwards, backwards	forwards	Specifies if the delay should be added from the beginning or the end of the selected elements.
