# HTML <frame> longdesc Attribute

HTML <frame> tag

## Example

The longdesc attribute points to a page with a long description of the content of a frame:

<frameset cols="50%,50%">
<frame src="frame_a.htm" longdesc="w3s.txt">
<frame src="frame_b.htm">
</frameset>

## Definition and Usage

The <frame> tag is not supported in HTML5.

The longdesc attribute specifies a URL to a page that contains a long description of the content of a frame.

Tip: The longdesc attribute is so poorly supported that it should not be used. To offer a long description of a frame (if necessary), simply create a link (that is visible to anyone) to a page with the description.
