I am still learning all there is to know about coding and design and am brand new to this forum.

I am hoping to get help with adding a close button to a popup banner that I recently created.

I have tried dozens of different snippets of code that I found in my searches, however, I either get no function at all, OR, most recently, it closed my entire browser instead of just the popup.

In addition, I am having trouble positioning the button in the upper right hand corner of the banner.

Seems simple, I know, but like I said, I'm still learning. :-)

So, if anyone can help, I'd greatly appreciate it and would love to learn something new.

My popup banner can be found on this live test page:


I also have the code in a jsfiddle here where I have been testing all of the codes: http://jsfiddle.net/tXumG/14/

This is the button image that I have been trying to use: http://online.saintleo.edu/media/150496/blue_white.png

Thank you in advance!
