What's the need for XHTML?

Asked 2009-02-17T17:22:11.463

In an interview I was asked a question that I'd never thought about, which was "We already have HTML which fulfills all the requirements of writing a web page, so what's the need for XHTML?"

I Googled a lot and also read many articles, but I'm not able to get properly why XHTML has been introduced. Please explain to me.

I am sure you mustve encountered this article from W3.There is a lot to learn from that article. In short XHTML abides the xml rules besides having HTML set of tags. The Most Important Differences:

* XHTML elements must be properly nested
* XHTML elements must always be closed
* XHTML elements must be in lowercase
* XHTML documents must have one root element
