Divs are not tables! (think foundations rather than houses)
there is no need to think about them in the same vein..why would a "stack" of divs take longer to render than a table? The div in the middle will render then the one outside that will render then the one outside that will render then the one outside will render....etc
have you anything on your page yet?
a table is entirely different not one bit of that will render until the whole outer thing has been built! (never mind the nests! (or walls))
ok, so here's what I probably should have asked -- I'm using a good bit of CSS, but still have many stacked tables. Instead of setting the alignment to center within each table I was going to wrap all of them in one <div align="center">. Would that div wrap defeat the purpose of the stacked tables?
I'm very interested to learn more on how to use <div>, but I'm concerned about browser compatibility. Anyone know what I need to worry about there?
