CSS - Equal Height Columns?
There seems to be many articles on the web, but many are not updated and I can't understand if there is really a BEST way to build 2 equal columns in CSS (without knowing which one of them will be the longest).
Example:
What I want to achieve is that column B will strech all the way to the size of column A. Also, if column B will be longer than column A, then I want column A to strech all the way to the size of column B.
Thanks

This should work, ive seperated the specific styles needed, and commented where possible.
Hope it helps.
