If your browser isn't JavaScript capable, think about upgrading to an HTML 4.0 capable version of your favorite. It's worth the effort. One valid way to use frames, in our opinion, is todisplay navigation aids. Links can then be visible at all times no matter where on the page the viewer might be. Frames and JavaScript are a particularly powerful combination.
Care is required with frames.
They have been, and still are, abused by many site designers. Frames can be confusing and awkward. There's another thing, too. Not all browsers support frames although the current releases from Netscape and Microsoft do. That means you have two copies of the same page on your server.
