Frames
With frames, you can display more than one HTML document in the same browser window. Each HTML document is called a frame, and each frame is independent of the others.
The disadvantages of using frames are:
The web developer must keep track of more HTML documents
It is difficult to print the entire page
The Frameset Tag
The frameset tag defines how to divide the window into frames
Each frameset defines a set of rows or columns
The values of the rows/columns indicate the amount of screen area each row/column will occupy
Above is the code used to obtain seperate frames.
Here is an example of 2 different frames below at 25% and 75%.
