HTML Tutorial

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 "a.html" is put into the first column, and the HTML document "b.html" is put into the second column:

<frameset cols="25%,75%">
<frame src="a.html">
<frame src="b.html">
</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.
