This is most commonly used on web sites that want to have a banner or directory always displayed, along with the particular content the user is browsing. Examples of web sites using frames include the ASLA home page , the Nando Times , and the United States History web site . Each of these sites has a directory frame along the left-hand side of the page. If you click on any of these links, you'll see how the document you are accessing is loaded in the main frame on the right-hand side of the window, but the directory frame remains unchanged.
Frames can be a powerful navigation tool if designed effectively, and used appropriately.
However they also present a number of problems. HTML documents that use frames are more difficult to author, because you can't create your main page in Netscape Composer. This is just a very basic introduction into frames, and is not meant to be all encompassing, but this page will help you get a basic understanding of how to use frames, and should give you enough to play around with to see how frames work. The closing tag is required. Creates a frame document with vertical columns.
