I'd like to know how to do what this person did... http://www.livejournal.com/userinfo.bml?user=khallandra

A colour box with an image on one side and a blurb of selectable text on the other side.

Could someone give me the html code for that?

Thanks, in advance!

That's just a table with two sides and the border set to 0.

Read there for the codes.
