Frames are intricate and can be very poorly implemented. To do the job right takes some time and planning along with a thorough understanding of how frames tags work--how each part of the frames site relates to the others.
Implementing frames is similar to planning a Web site, in that you must construct how a group of HTML documents related to one another, and they relate in a more complicated way than with a straight, hypertext-linked site. Don't let that stop you from experimenting, though.
Let's begin with the HTML coding for three different configurations of frames: horizontal, vertical, and nested.
