In many designs, we have two column. One for main content and the other is for sidebar. So, I float one to the right and the other to the left. Imagine that we apply a background to them. The problem is here that the height of main_content and the height of sidebar is not equal. My english is not good so see this as an example :? :
In css2 the display:table technique can solve this but it’s not supported by IE less than 8. :(
(sorry. I know it’s a very simple question but I didn’t know what should I search in the internet to find the answer. and, sorry for my English.)
The problem is that I don’t know how much the height of main_content would be. It depends on how much content will be there. If the content in main_content be more than the sidebar, the sidebar background doesn’t apply.
