Underscores is a minimalist starter theme designed for developers who build custom website themes. It provides a clean, standards-compliant codebase as a foundation, allowing developers to implement their own design and functionality without having to strip out unwanted features.

• Lean, Modern Codebase: Offers a just-right amount of well-commented, modern HTML5 templates and starter CSS. This minimal approach means less pre-built code to remove or override.
• Development-Focused Features: Includes practical development aids like custom template tags to prevent code duplication, a sample custom header implementation, and a responsive navigation script for small screens.
• Flexible Layout Options: Provides two sample CSS layouts in the /layouts/ directory for sidebars on either side of the content, giving a structural starting point.
• Clean Slate for Design: The ultra-minimal CSS is intentionally basic, described as 'theme tartare,' to avoid imposing design decisions and provide a blank canvas for your own styles.
• GPL Licensed: Released under the GPLv2 or later license, ensuring it can be freely used and modified to create new themes.
