Layout Builder in Drupal
The Layout Builder module for Drupal provides a layout user interface (UI), a set of flexible visual design tools that allows content creators and site administrators to customize the layout of a page via a powerful drag-and-drop UI. You can use Layout Builder to customize the layout of a single page, create a custom layout for all content of a certain type, or build landing pages.
The Web Starter Kit helps provide Principal Design System components for use with Layout Builder.
