Internet Explorer included a proprietary tag designated <iframe> in the v3.0 release to place a frame within a page. This technique, called inline frames or floating frames, originally worked only with Internet Explorer. The World Wide Web Consortium (W3C) included the iframe feature in HTML 4.01. Virtually all current browsers support inline frames(iframe).
<iframe name="inlineframe" src="float.html" frameborder="0" scrolling="auto" width="500" height="180" marginwidth="5" marginheight="5" ></iframe>
The above code produces the inline or floating frame below right which is in the righthand column of a table layout. For demo purposes, links are included to the left of the inline frame which target and change its content.
