Font Awesome Background color

Question

When using the brilliant Font Awesome, how can I make the icons not transparent - for instance if I want to use http://fortawesome.github.io/Font-Awesome/icon/chevron-circle

Answer 1

UPDATE: As xavier pointed out below, font-awesome has Stacked Icons which will let you put a circle behind an icon without using a hack. Essentially, you stack whichever icon you want on top of their fa-circle icon. You can then style the circle independently from the icon and change it to whatever color you'd like.

Here's an example based off of code from their site:

.fa-circle {
  color: black;
}

ORIGINAL ANSWER: Unfortunately, the whole icon is considered a single "character" on the page and as such, you don't have that granular of control over it. You can simply set a single "color" property to set the color of the character/icon to be what you want.

Now, it is possible for a creative hack though. Since the middle of the character is transparent, you can set a colored background behind the character to make it appear that the middle is a different color by doing something like this:

then in your CSS:

.fa-chevron-circle-up {
  background: yellow;
  border-radius: 50%;
  height: 1em;
  width: 1em;
}

If the background circle offsets the icon, you can use line-height to fix it.
