Aligning Web Parts

Is there a way to align web controls so they are side by side, but when they run out of width in the window they drop down to the next
line in the page?
I have various web parts that when adding to a WebPartZone from the catalogzone, they align horizontally, but when they get to the edge of the page they seem to just go off the page instead of dropping down to the next line.

Any suggestions would be great?

 

I'm a little confused. Are you referring to Visual Studio where it performs some kind of word wrapping function or are you referring to your website?
