HTML - 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 element holds two or more frame elements. Each frame element holds a separate document.
The frameset element states only HOW MANY columns or rows there will be in the frameset.
<frameset cols="25%,75%">
</frameset>
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_1.htm" is put into the first column, and the document "frame_2.htm" is put into the second column:
<frameset cols="25%,75%">
<frame src="frame_1.htm" />
<frame src="frame_2.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%,*").
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 <frame> tag.
Note: 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!
| Tag | Description |
| <frameset> | Defines a set of frames |
| <frame /> | Defines a sub window (a frame) |
| <noframe> | Defines a noframe section for browsers that do not handle frames |
| <iframe> | Defines an inline sub window (frame) |
