All standard HTML5 elements are listed here, described by their opening tag and grouped by function. Contrary to the HTML Element index which lists all possible tags, standard, non-standard, valid, obsolete or deprecated ones, this list only the valid HTML5 elements. Only the elements listed here should be used in new Web sites.
The symbol This element was added as part of HTML5 indicates that the element was added in HTML5. Note that other elements listed here may have been modified or extended in their meaning by the HTML5 specification.
