Underscores is a starter framework designed for developers who want to create custom themes from scratch on popular content management systems. It offers a clean, minimal codebase that serves as a foundation, allowing for rapid customization and efficient workflow without imposing design constraints.

• Lean, well-commented templates: The framework includes modern HTML5 templates with clear comments, making it easy to understand and modify the structure for your specific needs.
• Smart CSS organization: Starter CSS in style.css is organized to help you quickly implement designs, with minimal default styling that avoids getting in your way during development.
• Custom template tags and functions: Template tags in inc/template-tags.php keep code clean and prevent duplication, while functions in inc/template-functions.php offer small tweaks to improve the theming experience.
• Responsive navigation: A script at js/navigation.js enables toggled dropdown menus on small screens, providing a responsive base ready for custom CSS enhancements.
• Sample layouts and components: It includes 2 sample CSS layouts for sidebars, an optional custom header implementation, and a helpful 404 template to jumpstart common theme elements.
