Yes, I just put those <br />'s there to temporarily expand the window so it doesn't look too tiny. The assumption is that they would be replaced with real content like text or images. The formatting can be changed by modifying the appropriate css id or class. A further improvement would be to move the css into an external style sheet.
Btw, if you haven't already, put the file somewhere so that the background image is in the "images" folder.
I'm glad this helped. There is quite a bit that could be done to improve this however. Instead of a solid color, I would think of blending in some sort of texture that goes with the background image. Just have a solid color underneath the text to make it easy to read. The navigation could also use some help. You can get some ideas here:
