Page layout acting strangely

If you go on to my website, lookaroundyou.net and click on USA (which is where there are more video's than anywhere else on the site), the websites layout changes completely.

Does an开发者_如何学运维yone have an idea as to why this happens?

I don't want to visit your site if it's crashing Firefox, but if the problem is indeed due to more content causing a scrollbar to show up and thus changing your page width, one easy way to sort that is to always display a scrollbar (it will be disabled if there is not extra content below). In this way, the width of the page will be the same regardless of length.

<style type="text/css">
html { overflow-y: scroll; }
</style>

I'm sure there's some other non-standard setting with IE that will do the same; that's left as an exercise for you.

It's causing a scrollbar because there are more videos.

I'm using chrome and I don't see any difference other than the page shifts when the scrollbar on the right appears.....
