Navigation button
A single graphic image, generally in a GIF or JPEG format, that links to a single URL.
An element commonly used on framed pages. Content placed between the <noframes> and </noframes> tags display when a browser does not support frames or is configured not to display frames. Because almost all browsers support frames, search engines either ignore or place low weight on the content inside the <noframes> tags. Please see: Frames and search engine visibility.
If a browser does not support a scripting language or if an end user has disabled client-side scripting in a browser, content between the <noscript> and </noscript> tags is displayed. This element enables web developers to display alternative content in the event a script is not executed.
