I'm making a layout for my site, and I want my text to be in two boxes (they're not frames) just like this site: Click here .. (http://www.impulsive.nu/) (the box thing with the blog and the menu)

But, I don't know if this is an iFrame or something else.
Can anyone help?

It's Divs (http://www.``````````````/divtutorial.shtml) and tables (http://www.lissaexplains.com/table.shtml).

Thanx for the help!
