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
The Frame Tag
The <frame> tag defines what HTML document to put into each frame
In the example below we have a frameset with two columns. The first column is
set to 25% of the width of the browser window. The second column is set to 75%
of the width of the browser window. The HTML document "frame_a.htm" is
put into the first column, and the HTML document "frame_b.htm" is put
into the second column:
If a frame has visible borders, the user can resize it by dragging
the border. To prevent a user from doing this, you can add noresize="noresize" to
the <frame> tag.
Add the <noframes> tag for browsers that do not
support frames.
Important: You cannot use the <body></body> tags together with the
<frameset></frameset> tags! However, if you add a <noframes> tag containing some
text for browsers that do not support frames, you will have to enclose the text
in <body></body> tags! See how it is done in the first example below.
