pub struct Hgroup;
Expand description

The <hgroup> element - heading group.

§Purpose

The <hgroup> element represents a heading and related content (typically subheadings, alternative titles, or taglines). It groups a heading with secondary content like subtitles or taglines, treating them as a single heading in the document outline.

§Content Categories

  • Flow Content
  • Heading Content
  • Palpable Content

§Permitted Content Model

  • One or more <h1>-<h6> elements, optionally intermixed with <p> elements

§Common Use Cases

  • Grouping a title with a subtitle
  • Combining a heading with a tagline
  • Multi-line headings with different semantic levels

§Key Attributes

  • Global attributes only

§Example

<hgroup>
  <h1>HTML5 Elements Reference</h1>
  <p>A comprehensive guide to semantic HTML</p>
</hgroup>

§Accessibility

  • Screen readers treat the group as a single heading
  • Only the highest-ranked heading affects document outline
