CSS auto-view/hide products

I am looking for a css guru that is able to code dynamic content. The idea is simple: depending on the browser width, the number of shown products increases/decreases. For a live example check Amazon.com. On their frontpage, when you make the browser larger (in width), then the number of products shown auto-increases, and vice versa. This might be able by using the overflow property, but its important not to show any scrollbars, horizontally or vertically. Depending on the browser-width the products should auto-hide/view. Products should also not cut off partially. [login to view URL] shows exactly how the code should work. Im able to code basic CSS myself, but the auto-hide/view code is to advanced. Im looking for someone that can explain this to me. Regards
