Frames let a Web page show multiple documents.
By using them, we can split the browser window into numerous smaller windows. Each of these frames can contain an independent document, which can be changed as easily as one document can be. The construction of framed documents is more complex than with other HTML elements, we need a separate document just to create the frameset. The contents of each frame are normal HTML documents, although these documents may be frameset documents themselves. Sample Documents When demonstrating frames, we need to have a few pre-prepared Web pages that we can reference in the frameset document.
