Difference between XHTML and HTML

HTML and XHTML are the web languages. The main difference between the two is that HTML is based on SGML while XHTML is based on XML. To comply with XML standards, XHTML was derived from HTML. XHTML is strict to follow encoding rules compared to HTML. HTML-encoded pages looked different in different browsers, so XHTML was developed to complicate browser-specific tags.

What is HTML?

HTML stands for Hypertext Markup Language. It is used to create web pages. It is based on SGML. It has file extensions that are .html and .htm. It was proposed by Tim Berners-Lee in 1987. His Internet media types are text / .htm. The HTML format type is document file.

What is XHTML?

XHTML stands for Extensible Hypertext Markup Language. It is used to create web pages. It is based on XML and is derived from HTML. It has file extensions that include .xhtml, .xht, .xml, .html, and .htm. The origin of information technology comes from the recommendation of the World Wide Web Consortium in 2000. Its Internet media types are applications / xhtml + xml. The XHTML format type is Markup Language.
