How would I make all four columns reach down so they are all the same height?

Thanks

There are lots of answers to this around the place (Google “equal height columns”, for example, to find lots of solutions).

One simple option is to remove all the floats on the inner divs and do this instead:

#homepage {display: table;}
#homepage > div {display: table-cell; vertical-align: top;}
