Here is a demo of Cufon on my portfolio site, those headings with silver gradients are actually text replaced by Cufon on the fly.
The above lines of code will replace all your h1 elements with images rendered in your font.
You can take a look at a more detailed guide to replacing text with cufon here : http://wiki.github.com/sorccu/cufon/usage
You can also add linear gradients to your text with cufon!, here is how :
color: ‘-linear-gradient(#000, #777, #777, #000)’
The above code will cause the text to fade from black (#000) to grey (#777) and then back.For a comprehensive guide to styling using cufon refer to : http://wiki.github.com/sorccu/cufon/styling
So why wait? go ahead and try it out today, i bet its awesome and the easiest text-image replacement solution available right now, much simpler and better that sIFR.
