Underscores is a minimal starter theme designed for developers who build custom themes from the ground up. It provides a clean, standards-compliant codebase that serves as a foundation, allowing developers to implement unique designs without fighting against pre-built styles or complex features.

• Lean, Modern Codebase: Offers well-commented, semantic HTML5 templates and organized starter CSS. This structure provides a solid foundation while keeping file weight minimal, so you can focus on writing your own styles and functionality.
• Development-Focused Features: Includes practical utilities like custom template tags to prevent code duplication, a sample custom header implementation, and a responsive navigation script that converts menus for mobile screens. These are built as starting points for common theme requirements.
• Flexible Layout Options: Comes with two sample CSS layouts in a dedicated directory, demonstrating how to structure content with a sidebar on either side. This serves as a reference for implementing your own layout structures.
• Hackable Foundation: Explicitly intended to be modified directly, not used as a parent theme. The ultra-minimal default styling is intentionally basic, ensuring nothing gets in the way of your custom design process. It includes a helpful 404 template and small tweaks in template functions to improve the theming experience.
• Open Source License: Licensed under GPLv2 or later, providing the freedom to use, modify, and distribute your resulting work without restrictive licensing concerns.
