Center content on VP

I cannot figure out how to center the content on a vertically oriented VP. Panels are 600px wide and I'd like them centered.

I used to solve this by starting up AwareIM in a centered iframe. However on mobile devices using an iframe makes awareim unresponsive.

If any one has a good tip how to center VP's I'm interested as well.

Turned out that the Vertical Box layout is what I needed.

That won't center a top menu if you have it defined I guess

Kingsley, when you get it done, can you share a screenshot, to see exactly what you mean?

Thanks!
