Do you have a link to your site?

Yep, a link.. and a link to your CSS too.

There's a "dirty" trick to it... put negative a margin-top to the "content" class. You have to play with it tho, it depends on each skin ;) (That's why I call it "dirty" :p the real solution is to find the style(s) producing those spaces.)

Yes. that is working with negative value.
Thanks..

ps. not content, it was for main.

Thanks~~~
