XHTML

What is XHTML?

XHTML is a combination of HTML and XML (EXtensible Markup Language).

XHTML consists of all the elements in HTML 4.01, combined with the strict syntax of XML.

XML is designed to describe data, and HTML is designed to display data.

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
