Understrap is a free, open-source theme framework designed for developers who build custom websites on a popular content management system. It merges a clean, best-practices codebase with a widely-used front-end component library to provide a solid foundation for bespoke projects.

• Clean Starter Code: Built on Underscores, providing a simple, well-structured, and semantic codebase that follows modern development standards.
• Front-End Library Integration: Incorporates Bootstrap, offering a responsive grid system, pre-built components, and utility classes to accelerate front-end development.
• Lightweight and Performant: The framework is designed to be lean, avoiding unnecessary bloat to help create fast-loading websites.
• Child Theme Ready: Includes a child theme to safely make customizations and updates without modifying the core framework files.
• Open-Source with Commercial Support: Maintained as an open-source project by a professional development company, offering a balance of community-driven flexibility and dedicated maintenance.
