While they are not very common, loads of websites employ the use of Icon Fonts. They come with several pros and cons, but the pros outweigh the cons easily.
The obvious benefit of using icon fonts is the fact that they can infinitely be scaled. They can easily be styled with any CSS property including shadow, color and gradients. Moreover, it becomes significantly simper to modify one single font file instead of juggling around with several different fonts that you would otherwise have running on your website. Furthermore, a single font file would require the use of a single HTTP request. Finally, they do look impressive.
If you are convinced that using icon fonts are indeed an added advantage, you should browse through this list of 25 Fresh Free Icon Fonts Sets 2014. They are free obviously, so you don’t need to worry about the costs associated with them.
