I know of various ways to dynamically alter web pages’ typeface properties via JS/DHTML, or replacing text with Flash-rendered fonts (with sIFR or Cufon). However, I can’t find any good examples of dynamically changing the typeface used on a web page depending on user choice – with, for example, the use of a dropdown box or text links (to allow the choice of Arial, Helvetica, Lucida Sans and Gill Sans for example).
I’m sure I’ve seen this functionality in web sites before but I can’t find anything written about it, let alone real world examples! Can anybody point out some good examples / proof of concepts / sites that have successfully implemented this feature?
Not sure if this will work, but could you embed a little CSS in the head of your page and then use JavaScript to modify the “font-family” programatically? I’ve never tried that before so this is just a guess.
