Underscores is a minimal starter theme designed for developers and designers who build custom themes. It provides a lean, standards-compliant foundation to modify, avoiding the bloat and constraints of pre-built themes.

Lean Codebase: The theme offers a minimal amount of starter HTML and CSS. This reduces clutter and gives you full control over the final design without needing to override excessive default styles.

Modern Templates: It includes well-commented, modern HTML5 templates for standard site components. This provides a logical structure to build upon while keeping code clean and maintainable.

Development Utilities: Custom template tags and functions are organized in separate files. This promotes code reuse, prevents duplication in template files, and improves the theming workflow.

Responsive Foundation: A built-in JavaScript file handles basic responsive navigation, converting menus into toggleable dropdowns on small screens. This provides a functional starting point for mobile-friendly designs.

Flexible Layouts: The starter CSS is smartly organized and includes two sample layout stylesheets. These offer a starting point for common content-and-sidebar arrangements to accelerate development.
