Hi,
Today, I just made a little jQuery script that permits you to make your grid system’s boxes the same height on same lines : Equal Height
You just have to insert the equalheight class on each box that has to be resized and you’re done.
Examples are done with z-grid, a lightweight grid system I created but it can be used on a ton of other grid systems.
It is also available on github
Share, if you like my work :)
