In my web design, I have a page with three iframes on it. When a link points to the "nav" iframe, the appropriate "nav" page shows up. When a link present in the "nav" iframe points to a page in the "content" iframe, again, the appropriate "content" page displays correctly. So far, so good. My question is, how can I get an iframe to display a blank page (in this case, the "content" iframe should go blank when a new main link points to a new "nav" iframe page)? The reason is, the navigation could get confusing for visitors when the "nav" iframe changes to a new page but the "content" iframe page remains the same. This logic should follow so that the "content" iframe is dependant on clicking a link in the "nav" iframe. If a new iframe comes up, the "content" iframe shouldn't continue to display an older page. It's okay if it does, it's just that I think the navigation would be cleaner with either a blank page or some simplistic page showing.
Any thoughts or ideas?
