I am trying to design a layout that is masonry style. I am having trouble with two things:
1) How can I get my images to remain in the same order, even as the browser width changes, and the columns move around?
2) When the browser screen gets smaller, the columns fold into eachother, making them partially block the column before it. How can I avoid that?

Thank you...
