vBSEO.com Top Panel Drop Down

I am sure that this has been asked before. I have been searching the forums for the last hour with no success. Can someone please tell me how to make a top panel exactly like the one they have here on vbseo.com

The one that currently has the MAKE BETTER DECISIONS FOR YOUR COMMUNITY image in it with the + sign that expands it down.

This would be greatly appreciated as it would be an amazing addition to my website.

Also if you could explain how they dropped the logo table away from the top of the page and added rounded corners then things couldn't get better for me.

Thank you in advance!!

160+ views and no one can shed any light on this for me?

It's just some ordinary codes on HTML div with some css edits, You can do it by yourself or you can view the page source to see what we have done on it.
