Here is a super cool utility !
As a web developer i was usually stuck up when creating the initial framework for any site. As I was going through YUI, found this tool which builds whatever the layout you want. Even a 100% flexible layout !!!
On top of it you can write your own CSS also. Worrying about cross browser issues has been stopped at this point.
