Underscores is a starter theme designed for developers who build custom themes for content management systems. It provides a minimal, standards-compliant foundation that you can modify and extend to create unique designs without unnecessary bloat.

• Lean, Modern Templates: Offers a just-right amount of well-commented, semantic HTML5 templates. This clean starting point lets you focus on your design and functionality without wrestling with a complex pre-built theme.
• Organized Starter Code: Features smartly organized CSS and PHP functions. Custom template tags help keep code clean and prevent duplication, while separate files for custom headers and template functions improve the development experience.
• Responsive Navigation: Includes a script that automatically converts the main menu into a toggled dropdown on small screens. This provides a solid, functional base for implementing responsive design with your own CSS.
• Development-Focused Features: Comes with practical aids like a helpful 404 template and sample CSS layouts for sidebars. The ultra-minimal default styling is intentionally plain to get out of your way, allowing you to build your visual design from the ground up.
• Open Source License: Licensed under GPLv2 or later, giving you the freedom to use, modify, and distribute your creations. It's a trusted foundation used by many developers to build professional themes.
