How do I get this css header code to work on my myspace?

[justcallitanight]

Hello I was trying to add a heading to my myself and I wasn't able to get it to work, but I'm close, I was wondering if anyone could help me figure out what I'm doing wrong I tried it with top: 0 and the myspace ad banner shows over my image so I changed it to top 175 and then the image shows over my extended network banner etc..Do you know how I could get it to either show over the ad banner or in between the extended network banner and the home|music|movies etc links...this is the code I was trying to use...thanks for any help! body{ background-position:top center;margin-top: ;}div.Tbanner {top: 175;left: 49%;margin-left: -401px;width: 100%;height: px; position: absolute;} <br><br>
