Tutorial 14: You've been Framed, Part I - HTML with Style
The details of the invention of frames and the reasons behind them are a long story. In fact, it's such a long story, with so much to be said on the subject that I'm saving all of that for a separate Style Watch article on this and more. For now, it will suffice to say that back in the days of Navigator 2.0 and the big Feature Rush, someone in Netscape had this idea for frames, someone else liked it, and it was implemented. The rest, as they say, is history.
"So, what are frames?" ask those of you who only recently vacated the underside of a rock. Frames, dear reader, are a method of splitting a Web page into different sections, and having each scroll independently of each other, or not at all.
"What a great idea!" I hear you exclaim already. And, I am forced to concede, it is a great idea. There are many interesting uses for something like this. And, when executed properly, frames can add a lot to a Web site. But alas, this is not the case in today's Web.
The shrewdest among you may have noted that splitting a document into separate sections that scroll separately is a presentation issue, and not related in any way to the semantic content of the document itself. The very concept of scrolling has nothing to do with a document's semantics, but is tied to the idea of displaying an HTML document on a computer screen. All of this means that an implementation of frames should lie in the realm of CSS, and not HTML. Unfortunately for all of us, at the time that frames where first implemented, CSS was only a pipe dream, and frames were hacked into the existing HTML framework, as was the custom for all new features at the time.
However, mainly because of their erstwhile popularity, frames finally wiggled their way into the HTML 4.0 Specification. So they are bona fide HTML in some ways. The specification also took some measures to fix some of the more glaring problems with frames, but most of these adjustments remain unimplemented.
Regardless of all the reasons given above why you should not use frames, how they work is something you should learn. You might run into them at some point in the future through no fault of your own, and you may even (though this is hardly likely) have a legitimate need for them. So let's get to the point and take a look at how you use frames in HTML documents.
The first thing you need to do in order to create a framed Web page is create a frameset document. A frameset document is a special kind of HTML document that defines how many frames you're going to be using, and what their layout will be.
A while back I briefly explained what a Document Type Declaration is and how to use it. If you want a refresher, check out the relevant section in Tutorial 4. Frameset documents use a special DTD, and the Document Type Declaration to use for them is the following:
