My suggestion is to start looking at getResources, and getPage. With those you will be pulling the content into the grid. Css/html wise you just create a chunk to use with getResources and make it 220px wide, maybe 10px padding and 1px solid border. Then you just float them. And limit the nr of output with getResources.
Hey Wias!
Exactly you are right and for more resources you can find out form the CSS forums with clarified solution.
float is the magicword. listitems/sections with dimensions and CSS-property float: left.
