dimension convertor

[hearts_guardian]

I'm looking for the coding that will allow my site to convert automatically to fit different dimensions. As in... if I design it with my computer 800x600 and someone visits it who has a computer set in a 1024x768 mode.... my site will convert to fit their screen. Please help.

Size all structural elements of the page using '%' or 'em' as your unit of measure. % is relative to the user's viewport area, em is relative to their font size.

Have fun, cause this can get tricky if you want to do it well.
(And as if you don't :D )
