Underscores is a starter theme designed for developers who want to build custom themes from the ground up. It provides a clean, minimal, and well-documented codebase that serves as a foundation, eliminating the need to reverse-engineer or strip down bloated existing themes.

• Lean, Modern Codebase: Offers a just-right amount of lean, well-commented HTML5 templates and starter CSS. This minimal approach removes unnecessary defaults and opinions, giving you a true blank slate and less code to navigate or remove.
• Organized Development Structure: Includes smartly organized PHP files like custom template tags and helper functions. These keep your template files clean, prevent code duplication, and follow modern development practices right from the start.
• Responsive & Accessible Foundations: Comes with a JavaScript-powered navigation script that creates a toggled dropdown menu on small screens, providing a ready-made responsive behavior for your CSS to style. The baseline code emphasizes semantic structure.
• Practical Starter Components: Provides practical starting points like a helpful 404 template, optional sample code for custom headers, and two sample CSS layouts for sidebars. These serve as helpful references and building blocks rather than imposing a rigid design.
• Open Source License: Licensed under GPLv2 or later, ensuring you have the freedom to use, modify, and distribute your creations built upon this foundation.
