Theme Components

The theme exports a small component surface for docs authors. Most UI comes from Starlight component overrides installed by the plugin.

Imports

---
import { ContainerSection, Dropdown, LinkButton } from 'lucode-starlight/components';
---

LinkButton

ContainerSection

A layout wrapper that constrains content and adds responsive horizontal padding. It is useful on splash pages where you want full-width page sections that still align to the theme container.

This card grid is wrapped in a medium-width ContainerSection.

Responsive padding

The section increases inline padding across mobile, tablet, and desktop breakpoints.
