Sizing everything in EMs. Is it still worth the effort?

[ChrisBolton]

For the last year or so I have sized everything in my CSS files in EMS. This is mainly due to the fact that my browser of choice is Safari. The text zoom function in Safari 3 resized just the text, which resulted in a broken layout for the majority of websites.

Using this method reduces the amount of things you can do with design elements (unless you choose to add unnecessary DIVs), but in my opinion resizability is more important than aesthetics.

As IE7/8, Firefox, and now Safari 4 zoom the whole page when you change the text size, I'm wondering if it is still worth losing the aesthetics just to look after an ever decreasing number of bad browser users?

Any feedback would be appreciated.

Chris.

All I have to say about using EMs is that I personally think it's only useful with text size and line height and sometimes padding. I just think it's easier to use pixels with everything else. That way you get better cross browser compatibility. But when you get right down to it, that is more of a personal preference.
