Are you ready for a kick?

Good!

Here's the markup as shown in Mosaic 1.0, a very early graphical browser. There's no frames support, of course, but simply using the noframes element ensures that I can get to the information, as can the blind and mobility-impaired.

Because you can format an entire document within the noframes element, consider using the index page as the welcome page to your site. From there, link to internal pages that are external to the frame design.

NOTE

It's very important to remember that frameset documents do not support the body element, with this one exception: If the noframes element is in use, you use the body element as a means of creating the body information for the noframes version of your page. Otherwise, never use a body element in a frameset; use the frameset element instead.
