Underscores is a starter theme designed for developers who want to create custom themes from scratch on a widely-used content management system. It serves as a clean, minimal foundation that can be modified and extended to suit specific project needs, avoiding the constraints of pre-built themes.

• Lean, well-commented templates: The theme includes modern HTML5 templates with clear comments, making it easy to understand and customize the codebase without clutter.
• Smart CSS organization: Starter CSS in style.css is structured to help developers quickly implement designs, with minimal default styling that reduces interference.
• Custom template tags: Functions in template-tags.php keep templates clean by preventing code duplication and promoting reusable components.
• Responsive navigation: A JavaScript file enables toggled dropdown menus on small screens, providing a base for responsive design without extra complexity.
• Sample layouts and features: Optional layouts for sidebars, a 404 template, and custom header implementations offer practical starting points for common theme elements.
