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:
- 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> |
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 <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! See how it is done in the first example below.
