Cornerstone is a visual website builder that provides a unified workspace for designing and managing every part of a site, from pages to templates and global components. It is designed for users of all skill levels, from beginners creating their first site to professional developers working on complex client projects.

• Full-Site Visual Editing: Design and edit pages, headers, footers, archive layouts, and single post templates from a single, tab-based interface without switching between different tools.
• Component System: Create reusable design components with customizable parameters, allowing for consistent styling and efficient scaling across large sites or multiple projects.
• Dynamic Content & Query Builder: Pull in and display data from posts, custom fields, users, and external APIs. The visual Query Builder lets you create custom loops and display filtered content without code.
• Clean Code Output: The builder generates semantic HTML and structured CSS, avoiding proprietary shortcodes and unnecessary bloat. This results in better performance, accessibility, and easier collaboration with developers.
• Advanced Controls for Developers: Features like Breakout Mode for raw field editing, support for Twig templating syntax, and direct CSS/JavaScript editors provide granular control for custom implementations and advanced workflows.
