Underscores is a minimal starter theme designed for developers who want to build custom themes without the bloat of a full framework. It provides a clean, standards-compliant foundation that is meant to be modified and extended, not used as-is.

Key aspects include:

• Lean, Modern Templates: Provides a just-right amount of well-commented, HTML5 templates that serve as a solid starting point for any design.
• Organized Starter CSS: The smartly structured style.css file includes essential styles that help you begin your visual design quickly, without forcing a specific look.
• Custom Template Tags: Functions in inc/template-tags.php keep your template files clean and prevent code duplication for common tasks.
• Responsive Navigation: Includes a JavaScript file (js/navigation.js) that converts the main menu into a toggled dropdown on small screens, providing a responsive foundation.
• Sample Layouts & Code: Comes with optional sample layouts for sidebars and example code for features like custom headers, giving you practical references to learn from and adapt.
