WebFonts
- Glyphicons are images and not a font. All the icons are found within a sprite image
-
(also available as individual images) and they are added to the elements as positioned backround-images:
-
Actual font icons (FontAwesome, for instance) do involve downloading a specific font and make use of the content property, for instance:
@font-face {
...
src: url('../font/fontawesome-webfont.eot?#iefix&v=3.0.1') format('embedded-opentype'),
url('../font/fontawesome-webfont.woff?v=3.0.1') format('woff'),
url('../font/fontawesome-webfont.ttf?v=3.0.1') format('truetype');
...
}
.icon-beer:before {
content: "\f0fc";
}
-
As the content property isn't supported in older browsers, these also make use of images.

Here's an example of completely raw FontAwesome in use as a font, turning ( - you may not be able to see this!) into an ambulance: http://jsfiddle.net/GWqcF/2
