How do I create frames? What is a frameset?

Frames allow an author to divide a browser window into multiple (rectangular) regions. Multiple documents

can be displayed in a single window, each within its own frame. Graphical browsers allow these frames to be 

scrolled independently of each other, and links can update the document displayed in one frame without 

affecting the others.  

You can't just "add frames" to an existing document. Rather, you must create a frameset document that defines 

a particular combination of frames, and then display your content documents inside those frames. The frameset 

document should also include alternative non-framed content in a NOFRAMES element.  

The HTML 4 frames model has significant design flaws that cause usability problems for web users. Frames 

should be used only with great care.
