Rule HEAD-3
All subheadings (h2...h6) must contain text content.


Best Practice Type: Pass/Fail

All subheadings (h2…h6) must contain text content.


  • Text content includes all text nodes of children of the heading element.
  • Leading and trailing spacing characters are ignored. NOTE: If the text content is only spaces it will be treated as empty.
  • If an img element with an alt attribute is contained in a subheading (h2-h6) element, the alt attribute value is inserted into the subheading text content in the order of appearance in the document to become part of the text content of the subheading element.
