Hi, Teresa
I agree with with Mike about the web standards. It’s always a good starting point.
Also, I see you have embedded this rule in some of your pages:
body {
margin-right: 15px;
}
I believe you are trying to stop your content to be re-aligned when scrollbars appear or disappear, the problem you have is that not all browsers have the same scrollbar width.
There is not a simple way to fix that issue in all mayor browsers.
My suggestion is to develop more content to enrich the pages that are not tall enough to show a scrollbar on bigger screens. Poor content pages doesn’t look good anyway.
