Portfolio thumbnails drawing on top of nav bar?

If you scroll down to the thumbnails you’ll see that they draw on top of the nav bar. Can anyone tell me why?

I don’t know why, but my guess would be that images are downloaded and therefore they get get rendered last and appear on top of all other elements.

You can override it by setting z-index of .PixelArt to 0 and z-index of .NavBar to 1.

Also you are using head tag wrong.

Thanks, z-index worked. I’m still not totally clear on the proper head, body format.
