The provided mixins are intended to be used with the array-like variables

.icon-home {

.icon-email {

Example usage in HTML:

`display: block` sprite:
<div class="icon-home"></div>

To change `display` (e.g. `display: inline-block;`), we suggest using a common CSS class:

// CSS
.icon {
  display: inline-block;
}

// HTML
<i class="icon icon-home"></i>
