Two Column Theme, Help, to make both columns seperately Scrollable.

Question

Hey, I am not sure what to do on this one, I'm not a programmer, but trying to learn CSS as this is how the theme I am using was coded in.

I've gotten quite far on my own, but this one stumps me Its two column Theme... As far as I have been able to get, I can use the following:

#left {
   width: 235px;
   padding: 10px;
   margin-left: 20px;
   position: fixed;
   line-height: 15px;

If I change the position to Absolute, The whole page scrolls, If I leave it at Fixed, and add lets say, a Twitter feed, or other type of text that takes me past its reading where you would normally scroll, Its just cut off, cannot get to it, hightlight or scroll..

I've also toyed with the idea, of changing the theme to a 3 column theme, but Again, not a programmer, and i'd be really confused. anyhelp would be great...

Answer 1

I should note, that If its on Fixed, only the right side of page can be scrolled, and left side is locked..

Answer 2

try giving both columns a height and adding this:

overflow:auto;

This makes scrollbars appear on its container if the content overflows.
