vB4 Banner Ad Alignment
 

Hello folks, I'm totally new to the vBulletin community so pardon my question that is probably redundant. Anyhow, I created a banner that I placed on top below the navbar and it's aligned to the left. Is there anyone that can show me how to align it center? My html and css skills are pretty minimal but I'm trying to learn this stuff myself.

Your help would be greatly appreciated! Thanks in advance!
