HTML Frames
With frames, you can display more than
one Web page in the same browser window.
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="true" to the <frame>
tag.
Add the <noframes> tag for browsers that do not
support frames.
