HTML Frames

HTML Frames
With frames, several Web pages can be displayed in the same browser window. 
Attention !!  Do not expect frames to be supported in future versions of HTML.

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:

Frames are not expected to be supported in future versions of HTML
Frames are difficult to use. (Printing the entire page is difficult).
The web developer must keep track of more HTML documents

The HTML frameset Element

The frameset element holds one or more frame elements. Each frame element can hold a separate document.
The frameset element states HOW MANY columns or rows there will be in the frameset, and HOW MUCH percentage/pixels of space will occupy each of them.

The HTML frame Element

The <frame> tag defines one particular window (frame) within a frameset

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 document "frame_a.htm" is put into the first column, and the 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>

Note: The frameset column size can also be set in pixels (cols="200,500"), and one of the columns can be set to use the remaining space, with an asterisk (cols="25%,*").

Basic Notes - Useful Tips

Tip: 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 tag.

Note: Add the tag for browsers that do not support frames.&amp;amp;amp;lt;br /&amp;amp;amp;gt; &amp;amp;amp;lt;br /&amp;amp;amp;gt; Important: You cannot use the &amp;amp;amp;lt;body&amp;amp;amp;gt;&amp;amp;amp;lt;/body&amp;amp;amp;gt; tags together with the &amp;amp;amp;lt;frameset&amp;amp;amp;gt;&amp;amp;amp;lt;/frameset&amp;amp;amp;gt; tags! However, if you add a &amp;amp;amp;lt;noframes&amp;amp;amp;gt; tag containing some text for browsers that do not support frames, you will have to enclose the text in &amp;amp;amp;lt;body&amp;amp;amp;gt;&amp;amp;amp;lt;/body&amp;amp;amp;gt; tags! See how it is done in the first example below.&amp;amp;amp;lt;br /&amp;amp;amp;gt; &amp;amp;amp;lt;br /&amp;amp;amp;gt; &amp;amp;amp;lt;br /&amp;amp;amp;gt; &amp;amp;amp;lt;br /&amp;amp;amp;gt; &amp;amp;amp;lt;br /&amp;amp;amp;gt; &amp;amp;amp;lt;br /&amp;amp;amp;gt; &amp;amp;amp;lt;br /&amp;amp;amp;gt; &amp;amp;amp;lt;br /&amp;amp;amp;gt; &amp;amp;amp;lt;br /&amp;amp;amp;gt;
