HTML frame
Definition and usage
tag defines a specific window (frame) in the frameset.
Each frame in the frameset can set different properties, such as border, scrolling, noresize, etc.
Differences between HTML and XHTML
In HTML, the tag does not have a closing tag.
In XHTML, the tag must be closed properly.
Tips and Notes:
Note: If you wish to validate pages containing frames, make sure the doctype is set to "Frameset DTD". Read more about DOCTYPE.
Important: You cannot use the
tag with the
tag. However, if you need to add a
<![CDATA[ tag for browsers that don't support frames, be sure to place the tag within the <body></body> tag!</p>
