Website looks different in the same browser on MAC and PC

Question

For some reason my website looks different when viewed in the same browser but different operating system EX: MAC VS PC.

And forget about IE. It looks horrible. I was thinking of adding a custom css file just for IE.

It also looks different in chrome and in safari. I want all the versions to look like chrome "MAC".

The thing that specifically concerns me is the <div id=items> .

Answer 1

也许使用css框架来最小化渲染引擎之间的视觉差异？

Answer 2

You have a lot of absolute positioned elements like:

#sale_items, #viewed_items, #new_items {

Make sure anything that will be absolute is contained in a container with position set to relative that way your layout wont break and should be more consistent
