The latest syntax update to Font Awesome 4.0

This week, I decided to try out the latest version of Font Awesome - version 4.0. After updating, a couple of questions popped up in my mind:

  1. Since I have been using the mixin in previous versions and had just updated the name, I wonder if this is acceptable and legal considering all the name changes that I have noticed?

    @mixin fa-FontAwesome() {
  font-family: FontAwesome;
  font-weight: normal;
  font-style: normal;
  text-decoration: inherit;
  -webkit-font-smoothing: antialiased;
  *margin-right: .3em; // fixes ie7 issues
}

  2. I am still new to SCSS and Font Awesome, so can someone elaborate on the current syntax being used? Any information would be greatly appreciated.

    For instance, .#{$fa-css-prefix} incorporates a number sign and curly brackets within a class name. I am curious about the reasoning behind this approach.

Answer №1

  1. Your mixin is perfectly fine.

  2. That particular syntax employs string interpolation to establish the prefix for the base class of Font Awesome, which in this case is fa, using a variable.

For instance:

$fa-css-prefix: fa;
.#{$fa-css-prefix} { ... }

This will generate the following css:

.fa { ... }

This can be utilized as follows:

<i class="fa fa-camera-retro"></i>
.fa {
  &.fa-camera-retro {
  }
}

Theoretically, through variables, you have the flexibility to define your own prefix rather than strictly using fa.

Answer №2

The latest information on FontAwesome can be found on their website, make sure to check out the examples page here.
