postcss-each

A PostCSS plugin to iterate through values.

Iterate through values:

@each $icon in foo, bar, baz {
  .icon-$(icon) {
    background: url('icons/$(icon).png');
  }
}

.icon-foo {
  background: url('icons/foo.png');
}

.icon-bar {
  background: url('icons/bar.png');
}

.icon-baz {
  background: url('icons/baz.png');
}

Iterate through values with index:

@each $val, $i in foo, bar {
  .icon-$(val) {
    background: url("$(val)_$(i).png");
  }
}

.icon-foo {
  background: url("foo_0.png");
}

.icon-bar {
  background: url("bar_1.png");
}

Iterate through multiple variables:

@each $animal, $color in (puma, sea-slug), (black, blue) {
  .$(animal)-icon {
    background-image: url('/images/$(animal).png');
    border: 2px solid $color;
  }
}

.puma-icon {
  background-image: url('/images/puma.png');
  border: 2px solid black;
}
