Frames in HTML

The browser window can be used to display more than one document at a time. The window can be divided into rectangular areas, each of which is a frame. Each frame is capable of displaying its own document.
Framesets:

⇰ The number of frames and their layout in the browser window are specified with the <frameset> tag.
⇰ A frameset element takes the place of the body element in a document. A document has either a body or a frameset but cannot have both.

⇰ To create horizontal frames, rows attribute is used.
