Lately I have been very interested in how far we can take Typography only using CSS. Sure you can use images or sIFR to produce some very beautiful typography, but there is something unique and special about using only CSS. It is incredibly useful too, if you know the extent you can take CSS you end up with much more flexible websites— especially ones driven by a CMS.
There are a lot of great sites out there that have beautiful Typography using only CSS, however simply looking at them is only half of the picture. The best way to study it, learn it and apply it in your own designs.
