How to get different height html divs to float up

Answer 1

You should try placing each column of div's into it's own container, and float them left. For example:

    

        
asdf
        
asdf
    
    

        
asdf
        
asdf
    

etc, etc.

each column floats left against one another and each item in the columns flows vertically quite well... here's an example: http://jsfiddle.net/V6z8F/
