Counting elements with CSS
One of the big concerns I have with responsive design is what to do with "orphans" when screen sizes change. ie. If may have a grid layout of "featured products" on a home page where my designer has mocked it up with 4 columns... When the screen size changes, it would be better to show then in a 3 columns -but that extra item is now on a row by itself messing with the whole layout of the home page. What to do?
