Sane CSS Typography
Added on Tuesday 15 Jul 2003
Owen Briggs has spent a lot of time wrestling with the problem of accessible, controllable text sizes on the web - and this is what he has come up with : sane CSS Typography
I've spent time thinking about accessible web typography myself, and generally try to avoid advocating 'workarounds' , when a more straightforward, standards based (and usually easier to remember) solution will suffice. For this reason I prefer to use em units for setting text size; ems are a relative unit that give control of text sizes to the user.
However Owen's approach has has an attractive simplicity, so it is definitely worth considering when you are wrestling with the 'text size' problem yourself.
