Sorry, couldn't handle your loooooong registration form. What you can do is this -- go in management mode, and add a new element, an RTF box. Delete all text from the RTF and place it directly under the top global area. It will look like a thin horizontal line. Then click to edit and click the "Source" button then add:
If you want to affect only the one page you put it under the top global. To affect all pages that have the top global, put in in the top global under the nav bar. The reason for this technique is that the style can be changed in a few seconds. If you like what you see, you can just keep it that way.
We use this technique a lot, for example, see http://www.ardent-webs.spruz.com/home.htm and http://www.antigravity.spruz.com/.
