horizontal aligning header blocks

Hi, i just can't figure out how to do this:

In my header, I have two blocks: one with the localizer flags, and the login block, like this:

**localizerflags**********
**login_box*************

I just want to horizontal align them:

**localizerflags***login_box***

I spent 2 hours working on the css and I didn't make it. I tried floating, inlining block-elements, adjusting width, etc..

Am I missing something ?

thanks
