I would like to share something that I have recently discovered, Google Fonts. It is awesome!. It will definitely change the way your website looks significantly. Worth to try! Usage is very simple, you can use it with WordPress/Joomla/Drupal etc.

font-family: 'Droid Serif', Arial, Helvetica, Sans-Serif; font-size: 1.5 em;
