Underscores is a starter theme designed for developers who want to create custom website themes from scratch. 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.

Key features include:

• Lean HTML5 templates: A just-right amount of well-commented, modern templates that reduce clutter and provide a solid base for customization.
• Smart CSS organization: Starter CSS in style.css is structured to help you quickly implement designs, with sample layouts for sidebars to guide layout choices.
• Custom template tags: Functions in inc/template-tags.php keep templates clean and prevent code duplication, improving maintainability.
• Responsive navigation: A script at js/navigation.js enables toggled dropdown menus on small screens, ready for styling to match your design.
• Helpful utilities: Includes a 404 template, optional custom header implementation, and tweaks in inc/template-functions.php to enhance the theming experience.

All code is licensed under GPLv2 or later, encouraging open use and modification. This theme is ideal for those who prefer hands-on control over their theme's structure and appearance, offering flexibility without imposing design decisions.
