Documentation covering modern HTML elements and patterns that replace older, more complex implementations.

Why Modern HTML?

• Better accessibility - Built-in keyboard navigation and screen reader support
• Less code - No JavaScript required for many interactive patterns
• Better performance - Native browser implementations are optimized
• Consistency - Standard behavior across applications
