Is the Ending Slash Optional?

  • HTML5: the slash is optional.
  • HTML4: the slash is technically invalid. However, it's accepted by W3C's HTML validator.
  • XHTML: The slash is REQUIRED.

I recommend to always add the slash. Because, it provides a visual clue of non-closing tags. It's also convenient if you write simples scripts to check your HTML, without a lookup table or using heavy HTML parser.
