The <frameset> is an HTML element which is used to contain <frame> elements.
The <frameset> tag defines how to divide the window into frames. The rows attribute of <frameset> tag defines horizontal frames and cols attribute defines vertical frames. The <frameset> element was used to create a group of frames which could be styled and controlled as a unit. Frames have been deprecated and should no longer be used.
The <frameset> element holds one or more <frame> elements. Each <frame> element can hold a separate document. The <frameset> element specifies HOW MANY columns or rows there will be in the frameset, and HOW MUCH percentage/pixels of space will occupy each of them.
Each frame is indicated by <frame> tag and it defines which HTML document shall open into the frame. The FRAMESET element is a frame container for dividing a window into rectangular subspaces called frames. In a Frameset document, the outermost FRAMESET element takes the place of body and immediately follows the head.
Syntax
