CSS for Grid/Masonry Layout

Need help with CSS for grid/masonry layout. I'm using a map program that has grid listings available only in masonry format. Because of long/short titles, this throws my layout off and items at the bottom float all over the place (left, center, right) because of the differences in height. Would like someone with CSS knowledge to make the grids the same height so they float correctly. [login to view URL] - Floats right [login to view URL] - Floats center at bottom [login to view URL] - Floats both left and right at bottom I appreciate your help in advance.
