Header not fitting

This is how it looks with the original one:

Also, if someone can link a nice looking theme I would appreciate that as well.
This is obviously my first website and I don't really know much about this, but I would love to learn more of it.

I believe that you should use CSS to make it fit in every browser, or to make sure your page layout is correct. There may be something that is stretching out your title.

Perhaps you should try resizing it, if you made it larger somehow?
