[thelist] FW: css font sizes

>Hi all...
>I hope someone here has gone through what I'm going through today...

>I've been give the job of making a collection of HTML pages comply 
>with w3c accessibility guidelines. From what I've read at the w3c 
>site http://www.w3.org/TR/1999/WAI-WEBCONTENT-19990505/ this is 
>best achieved by separating content from formatting as much as 
>possible. Tables are replaced with positioned divs for placement, 
>not to mention defining type with CSS. Which leads me to my question...
>What 'unit' or method is BEST for relatively sizing fonts with 
>CSS. I've been experimenting with em and smaller | small | medium 
>| large | larger. And can achieve pretty predictable results in 
>graphical browsers. I'm just wondering what I should be looking 
>out for and how to make sure I don't code pages into invisibility 
>in 'alternative' browsers...
