Entrepreneur and designer Ross Johnson has published a nice study of CSS typography on his personal blog. The article reviews ways of creating beautiful type designs using only the capabilities of style sheets, without any images. The CSS code for all examples is provided.
From the article:
"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."
