postcss-sass-each's Introduction

postcss-sass-each

A PostCSS plugin to iterate through values. Inspired and based on postcss-each. Support usage postcss-simple-vars before this plugin and sass-like @each;

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 (auto add index variable):

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

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

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

Iterate through lists with multiple variables delimited with colon:

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