A text-based navigation structure is under development. You browser should also be able to display tables correctly. This is probably because your browser does not support tables. This HTML extension allows us to format the page with multiple columns, align text neatly, etc. Frames are similar to tables, but have much more versatility.
Frames break up a page into several mini-pages on one screen, and each can act independently.
You must be using Netscape or Microsoft Internet Explorer 2.0 or higher to see frames. Plug-ins are software programs that extend the capabilities of web browsers in a specific way, allowing you, for example, the ability to view Adobe Acrobat files from within a browser. The Adobe Acrobat Reader allows a user to view files created in the Acrobat format. The Acrobat format is an Internet standard format for sharing documents. Many of the downloadable documents on the TEMA web site are in the Acrobat format.
