Screen Resolution

I was writing an article on my site when the screen resolution changed 4 or 5 times before it became very large. Not having this problem any place else. When I visit my web page it is the same way but no other site is affected like this.
My URL is http://badmoonowl.com
If anyone can help it would be appreciated. I believe someone has been trying to hack my site as 404 errors to log in has been abundant the last 2 weeks.
