I quite like to provide a baseline font size with an absolute measure, and then use a widget (server side best for accessibility) to allow users to pick a font size of their choice, overriding the baseline style sheet.

Store their preference in a cookie and they’re happy.

Of course, now Firefox 3 and IE 7 are zooming, rather than doing a strict font resize, (which works great on our site by the way), everything can grow – fonts know their places in boxy designs, because the boxes grow with them.

Of course, that doesn’t save the users of older browsers, but its an interesting development. If zoom becomes a more universal standard, will designers be off the hook?
