Alternative to CSS Propety; overlflow:auto

[anotherguy159]

I'm curious as to the different ways of handling overflow of text in CSS.

I enjoy the scroll bar the 'overflow:auto' generates and such, but I'm curious as to whether it would be better to simply allow the text to run down?

Should I set a fixed height? How would I handle the overflow? Is there a way to set the minimum height?

EDIT: Also, is there any way to make the 'top bar' a limited width?
EDIT2: Nevermind above edit.
