Underscores is a starter framework designed for developers who want to build custom themes from scratch on popular content management systems. It offers a clean, minimal codebase that serves as a foundation, allowing you to focus on design and functionality without starting from zero. This tool is ideal for experienced developers or those learning theme development who prefer full control over their projects.

• Lean, well-commented templates: The framework includes modern HTML5 templates with clear comments, making it easy to understand and modify the code for your specific needs.
• Minimal starter CSS: Smartly organized CSS in the style.css file helps you quickly implement your design ideas, reducing setup time and avoiding unnecessary styles that can slow down customization.
• Custom template tags and functions: Files like template-tags.php and template-functions.php provide reusable code snippets that keep your templates clean, prevent duplication, and improve overall theming efficiency.
• Responsive navigation script: A JavaScript file handles menu toggling for small screens, such as mobile devices, offering a ready-made solution that you can style with CSS to match your theme's look.
• Sample layouts and optional features: The framework includes sample CSS layouts for sidebars and optional implementations like custom headers, giving you flexibility to experiment and build upon a solid base without extra complexity.
