HTML frame longdesc attribute
Examples
longdesc attribute points to a page with a long description of the frame contents:
<frameset cols="50%,50%">
<frame src="frame_a.htm" longdesc="w3s.txt">
<frame src="frame_b.htm">
</frameset>
<frame src="frame_a.htm" longdesc="w3s.txt">
<frame src="frame_b.htm">
</frameset>
try it"
Browser Support
Almost all of the major browsers do not support the longdesc attribute.
Definition and Usage
HTML5 does not support the <frame> tag.
longdesc attribute specifies the URL to a page, the page contains information about the long description of the frame contents.
Tip: Because of browser support for the longdesc attribute is very poor, there is no need to use this property. To provide a long description for a frame (if necessary), simply create a link to a page description (the link is visible to anyone).
grammar
