Underscores is a minimal, semantic starter theme designed for developers who build custom website themes from the ground up. It provides a lean, well-structured codebase that serves as a blank canvas, allowing for complete creative control without the bloat of pre-built designs or complex frameworks.

• Lean, Modern Codebase: Offers a just-right amount of lean, well-commented, modern HTML5 templates and starter CSS. This organized foundation helps you start your design quickly without having to strip away unwanted styles or features.
• Development-Focused Features: Includes practical development aids like custom template tags to keep code clean and prevent duplication, a helpful 404 template, and sample custom header implementation. These elements streamline the theme-building process.
• Responsive & Accessible Foundation: Comes with a navigation script that converts menus into toggled dropdowns on small screens, providing a ready-made responsive behavior. It also includes sample CSS layouts for sidebars, giving a structural starting point.
• Hackable by Design: Explicitly intended to be modified and extended, not used as a parent theme. Its ultra-minimal styling is meant to get out of your way, offering a true starting point for creating a unique, custom theme.
• Open Source License: Licensed under GPLv2 or later, ensuring you have the freedom to use, modify, and distribute your creations based on this starter code.
