Ever since I've started posting here I've had @deathshadow60 on my back about accessibility - which is a good thing as I would of never considered it otherwise. And as a result I've been trying to avoid javascript as much as possible and have been using em heights.

But I've been doing some reading:

http://stackoverflow.com/questions/5...-accessibility
http://www.brucelawson.co.uk/2011/ja...screenreaders/

These articles state that all modern browsers can zoom correctly with pixel-sized fonts and only 1.6% of those using screen readers have js disabled.

Do you agree with these articles, in that I can go around setting fixed-pixel fonts and using javascript without worrying about it affecting accessibility? Are these accessibility concerns over a decade old?
