So this is literally the first time I've coded anything more complex than a forum signature. I know it's really really basic, but I'd like to know if it looks ok on your browser/screen? most likely it won't, but worth a try ^_^

Here!

It's very basic, but it's a lovely first try! If you could go in photoshop and add some borders around the column it'd help make it look a bit more fancy. If that's what you're going for ^_^

Looks fine to me!

My only suggestion would be modify the treasure chest box so that it's more obvious that it's scrollable (e.g: make the scrollbar always visible or add arrows or something). It was only when I noticed that the very bottom edge of some items were cut off that I realised there was more to it than the first five rows.
