Using percent for font size?

Question

I\'ve read a fair bit about resizing fonts recently, most of it deriding using px as an unforgivable crime (ok, maybe not that bad, you get the idea) because it doesn\'t res

Answer 1

There's a jQuery plugin called FitText. It resizes text based on percents. If the visitor for some reason has JavaScript disabled, it'll just display as normal, so set a reasonable PX or EM backup.

It depends on jQuery, so you'll need to include that in your page (if you don't have it already).
