And another thing…

The boundaries of my PNG (the logo in this site-in-progress) overlap a few of the menu items in the navigation bar: Home, About Us, and the left side of Construction. I applied a z-index to that navbar thinking that might solve the problem but it didn’t.

Another developer pointed out that the navbar needed to have positioning before z-index will work. I applied a position: relative; to it, and voila! Works perfectly now.
