  • To prevent the footer’s heading from becoming the page heading we can wrap the footer element’s contents in a section element:
  • This really feels like a hack, but it does move the footer heading to its expected position in the document outline.
  • Since there is no heading in the nav element, it becomes “Untitled NAV”.

  • An article with a title and metadata

  • An article with a title, subtitle and metadata
  • ...4 more annotations...
  • If you have a title with subtitle(s) and other metadata associated with the section or article, place both the <hgroup> and the metadata within a single <header> element.
  • If you have a title with subtitle(s) or tag lines (i.e., more than one consecutive <h1>–<h6>), group them in an <hgroup>.
  • When grouping headings in an <hgroup> element, the outline algorithm will mask the lowest level all but the highest level heading in the group from the resulting document outline.
  • It can only contain a group of <h1>–<h6> element(s), and it should be used for subtitles, alternative titles, and tag lines.

semantic structure headings html5

shared by Vernon Fowler on 10 Dec 12 - No Cached
  • The sectioning elements act quite literally as their name suggests: they define sections of the parent element. These sections can be thought of as child nodes whose headings fall under their parent heading, regardless of their rank.
  • Sections may contain headings of any rank, but authors are strongly encouraged to either use only h1 elements, or to use elements of the appropriate rank for the section’s nesting level.
  • For accessibility reasons, we recommend each sectioning element have a heading, even <aside> and <nav>, as shown below. If you don’t want these headings to be visible, you can always hide them with CSS.
  • ...2 more annotations...
  • It’s best if you use logical heading levels — <h1>–<h6> — at least until the new outlines are more widely supported.
  • Unfortunately, there is little support for the new outlining algorithms right now. Search engines may be experimenting with it in their crawling algorithms as you read this, but as far as we know, headings are treated just as they were before. You won’t be penalised for using them, even if you use multiple <h1>s (which have always been okay as far as the spec is concerned). Check out our HTML5 and Search Engine Optimisation article for more on search engines and HTML5.

section html5 html element markup outline document structure

shared by Vernon Fowler on 23 Jan 14 - No Cached
  • A general rule is that the section element is appropriate only if the element’s contents would be listed explicitly in the document’s outline.
  • The theme of each section should be identified, typically by including a heading (h1-h6 element) as a child of the section element.
  • Don’t use it just as hook for styling or scripting; that’s a div
  • ...2 more annotations...
  • Don’t use it unless there is naturally a heading at the start of the section
  • As blogposts and comments are often syndicated (by being pulled into other blogs or being linked via twitter, reddit etc) they should be articles.

  • The value of input elements whose type attributes are in the Text, Search, URL, or E-mail states and that are mutable (i.e. that do not have the readonly attribute specified and that are not disabled).The value of textarea elements that do not have a readonly attribute and that are not disabled.

      Note the input types that we can set spellcheck="false" include: email url search text
  • Otherwise, if there is an ancestor element with a spellcheck content attribute that is not in the default state, then: if the nearest such ancestor's spellcheck content attribute is in the true state, then checking is enabled; otherwise, checking is disabled.
  • User agents should take into account the other semantics given in the document when suggesting spelling and grammar corrections. User agents may use the language of the element to determine what spelling and grammar rules to use, or may use the user's preferred language settings. UAs should use input element attributes such as pattern to ensure that the resulting value is valid, where possible.
