In Orange County web design, normal HTML pages have only one address at which they can be reached. However, frames are composed of several sub-pages, where usually the address of the frame definition is displayed (the frameset) in browsers that do not change when switching to a different base in the rule. If anyone tries to link to a particular subpage, bookmark it or to specify it in an e-mail, it is usually a dilemma.
The frameset defined in the frameset instead of the desired base is loaded, it indicates the direct address, thus omits the other components in the page such as the navigation. This is confusing, especially for technically less savvy users who are accustomed to the basic principle of an address. Thus, for example, scrolling a content frame, not scroll the navigation and other important areas in their own frame.
