Frames, graphics within the navigation, and a cluttered HTML source code also complicate the right interpretation of your website by search engines. Fixed screen resolution and fixed defined font size not only prevent people with visual impairment to read the website, they also prevent the correct displaying of the websites on PDAs. The use of Javascript (e.g. in DHTML based navigation menus) inhibits the correct navigation on websites via PDAs, for security sensitive users without activated Javascript and Screen Readers likewise.
