Today I saw this and wondered why the class names were wrapped in brackets. The class names in the CSS do not have the brackets. Do the brackets offer any benefit?
<svg class="[ icon ] [ fancy-link__icon ]"...
Which had this accompanying CSS:
.fancy-link__icon {
font-size: 1.5em;
}
.icon {
width: 1em;
height: 1em;
}
