scrollbar does not appear as I ment

[Gerard]

Hello Bakers,

On a site I'm working on, customer want to have a scrollbar in the left-colom. It has to resize when a visitor resizes his browserwindow. So I made the scrollbar in css using overflow: scroll; and set the height of the block at 100%. The scrollbar appears but when I resize my browserwindow, the lower-arrow dissapears. And in full heigth it doesn't reach the bottom of the windows. How can I solve that?

Thanks in advance,

Gerard

To solve this you will have to do something in javascript.
CSS will not know the browser resizes. (javascript does)

Google is your best friend for these kind of issues. (search for something like: resize scrollbar javascript)
