I'm having an issue here;
http://roblb.devour.org/march2014/
Basically, what's happening is that as soon as I add any CSS to put some form of padding around the elements, it knocks things out to two columns, rather than three for the main images.
Removing the attribute;
.project {padding-bottom:0px; padding-right:0px; padding-left:0px; margin:1px;}
Makes the layout go to the correct three columns. I know I'm missing something, but i think I'm having one of those moments!
