For example, text that renders in one position can overlap neighboring text when the font size is scaled, making readability difficult.

Some people prefer to have the navigation elements at the end of a Web page.
For instance, people using screen readers want to hear the contents of the page before sifting through navigation. Note, however, that this only works with Internet Explorer version 5. In Internet Explorer 4.0 and later, Web designers can establish keyboard shortcuts that make Web pages accessible to people who can't use a mouse. Acronyms or abbreviations, which sometimes confuse screen review utilities, are a good example. A page designer can, for example, set the tab order so the main content of the page takes focus first and all the navigational elements take focus afterwards.
