Underscores is a minimal starter theme designed for developers who build custom themes for content management systems. It provides a clean, well-documented codebase as a foundation, eliminating the need to start from scratch or strip down a heavy default theme.

Key features include:

• Modern HTML5 Templates: A lean set of well-commented templates that follow current standards, giving you a solid structural base.
• Organized Starter CSS: Smartly organized CSS in the main stylesheet helps you implement your visual design quickly without fighting unnecessary default styles.
• Custom Template Tags and Functions: Includes separate files for template tags and helper functions to keep your template files clean and prevent code duplication.
• Responsive Navigation: Comes with a JavaScript file that converts the main menu into a toggled dropdown on small screens, providing a responsive starting point.
• Sample Layouts and Components: Offers optional sample implementations, like a custom header and two sample CSS layouts, along with a helpful 404 template, to guide development.
