Accessible Expand/Collapse Widgets
This page demonstrates two common patterns for expanding and collapsing content, ensuring keyboard accessibility and screen reader support.
1. Native HTML <details> and <summary>
The native element handles the toggle state, keyboard interaction (Enter/Space), and accessibility properties automatically.
What is Web Accessibility?
Web accessibility means that websites, tools, and technologies are designed and developed so that people with disabilities can use them.
2. Custom Disclosure Component (ARIA Pattern)
This version uses aria-expanded and aria-controls to provide state information to assistive technologies.
