Underscores is a starter theme for content management systems, intended for 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 familiar with theme development who prefer full control over their code.

• Lean, well-commented templates: The theme includes modern HTML5 templates with clear comments, reducing clutter and making it easier to understand and modify the structure for custom designs.
• Minimal starter CSS: Smartly organized CSS in style.css provides a basic starting point that helps developers quickly implement their own styles without having to override excessive defaults.
• Custom template tags: Functions in inc/template-tags.php keep templates clean by preventing code duplication, promoting maintainable and efficient theme development.
• Responsive navigation: A script at js/navigation.js enables toggled dropdown menus on small screens like phones, offering a responsive foundation ready for custom CSS enhancements.
• Sample layouts and features: It includes optional samples such as a 404 template, custom header implementation, and two CSS layouts for sidebars, giving developers practical examples to adapt or build upon.
