HTML 5 versus XHTML 1.0 Transitional

HTMLWeb DevelopmentFront End Technology

HTML is expressed as SGML and XHTML is expressed in XML. Creating XHTML is connected with more restrictions in the form of markup.

Avoid using the <video> or <audio> tags in XHTML 1.0 Transitional, as those are not an element of that specification.

Convert from HTML to XHTML

  • Add an XHTML <!DOCTYPE> to the first line of every page
  • Add a xmlns attribute to the HTML element of every page
  • Change all element names to lowercase
  • Close all empty elements
  • Change all attribute names to lowercase
  • Quote all attribute values
