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:
<frameset cols="25%,75%">
<frame src="frame_a.htm">
<frame src="frame_b.htm">
</frameset>

Basic Notes - Useful Tips
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.
