Underscores is a starter theme for content management systems, aimed at developers who want to build custom themes from scratch without unnecessary bloat. It serves as a clean foundation that can be modified and extended to suit specific project needs, making it ideal for those who prefer full control over their theme's code and design.

• Lean, well-commented templates: The theme includes modern HTML5 templates with minimal CSS, reducing clutter and allowing developers to focus on customization without wrestling with pre-styled elements.
• Custom template tags and functions: Organized files like inc/template-tags.php and inc/template-functions.php help keep code clean, prevent duplication, and improve the theming workflow with reusable snippets.
• Responsive navigation: A JavaScript file at js/navigation.js enables toggled dropdown menus for small screens, providing a mobile-ready base that developers can style with CSS as needed.
• Sample layouts and CSS: Two sample CSS layouts in the layouts/ folder offer sidebar options, while the starter style.css is smartly organized to help kickstart design projects quickly.
• Open-source licensing: Licensed under GPLv2 or later, it allows free use, modification, and distribution, encouraging collaboration and innovation in theme development.
