Examples

Use Subhead as the start of a section. The :heading slot will render an <h2> font-sized text.

Optionally set the :description slot to render a short description and the :actions slot for a related action.
Use a succint, one-line description for the :description slot. For longer descriptions, omit the description slot and render a paragraph below the Subhead.
Use the actions slot to render a related action to the right of the heading. Use Button or Link.

Accessibility

The :heading slot defaults to rendering a <div>. Update the tag to a heading element with the appropriate level to improve page navigation for assistive technologies. Learn more about best heading practices (WAI Headings)
