CSS starting question

Why doesn't bg and title overlap?

Use . instead of # or change class= to id=

I recommend the latter because I assume that bg and header unique .

 <img id="bg" src="bg.jpg"/> <img id="header" src="header.png"/>

See here for more details.

Two images in html got classes, while in your css you define styles for identifiers.

If the element has a class, set it in css using .classname if it has a target identifier using #idname. If an element only appears once in html, use id. If there are several cases, use a class.

I would also suggest for 2 elements that use the same basic properties to define them:

 #element1, #element2 { /* css properties */ }

This will save space on your css file and can be quite a lot.
