CSS & Font Sizes

[Mark]

I'm just after a bit of wisdom here.

If I specify something like

body { font-size: 1em; }

is this really the same as

body { font-size: 100%; }
?

Which is preferred, or is it a matter of taste?

And what is the difference between the above and not specifying the
font-size at all?

Thanks

Mark

They give the same result.

100% is preferred, due to a bug in IE6 and lower (maybe 7 too?) where em
unit will not scale correctly when user changes size (Medium to Large,
etc).

And what is the difference between the above and not specifying the
font-size at all?

None, except if you do declare it, you show your intent on being
correct. <g>

Also, if you do use em units elsewhere in the stylesheet, IE will give
more predictable results if you set font-size:100% first.

Thanks for your help. I wasn't aware of the IE bug so that simplifies
things.
