Overview

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 succinct, 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 <%= link_to_component(Primer::ButtonComponent) %> or <%= link_to_component(Primer::Beta::Link) %>.
