Underscores is a minimal starter theme designed for developers who want to create custom themes from a clean, hackable base. It's ideal for those who prefer to build without the constraints of pre-built frameworks, offering a foundation that can be tailored to specific project needs.

Key features include:

• Lean HTML5 templates: Just the right amount of well-commented, modern code to avoid clutter and focus on customization.
• Smart CSS organization: Starter CSS in style.css helps you quickly implement designs, with sample layouts for sidebars.
• Custom template tags: Functions in inc/template-tags.php keep templates clean and prevent code duplication.
• Responsive navigation: A script at js/navigation.js enables toggled dropdown menus on small screens, ready for styling.
• Helpful extras: Includes a 404 template, optional custom header implementation, and small tweaks in inc/template-functions.php to improve theming workflow. Licensed under GPLv2, it's free to use and modify for any project.
