How might I force a floating DIV to match the height of another floating DIV?

Question

My HTML code is just dividing the pages into two columns, 65%,35% respectively.

Answer 1

If you are trying to force a floating div to match another to create a column effect, this is what I do. I like it because it's simple and clean.

    
    
column a
    
column b
Line 2
Line 3
Line 4
Line 5
    
Column C
    

I think this makes sense. It seems to work well even with dynamic content.
