HTML - Frames

http://www.htmlhelp.com/design/frames/whatswrong.html

What's wrong with frames?

…

In depth

Unaddressable resources

On the Web, everything can be accessed (or addressed, at least) using an Uniform Resource Locator (URL).

This makes it possible to link to anything, anywhere. At least, as long as the anything in question does not use

frames.

Totally incompatible

The general rule for HTML is that if an element is not understood by a browser, it should be ignored. This way,

a browser that does not understand the element can still show the rest of the document. The reader may miss

some of the meaning of the text, or get a document that is formatted a bit strangely. Unfortunately, this is not the

case with frames.

The FRAMESET and FRAME elements do not have textual content. A browser that does not support frames

will simply skip over these tags. But as there is nothing else to show, this browser would display nothing in

place! The NOFRAMES element allows an author to specify content for such a browser, but this often means

that the author has to do double work.

AVOID FRAMES !
