Expand/Collapse Widgets

Accessible widgets provide clear focus styles, keyboard operability, and accurate ARIA attributes. Keep the button text updated so screen reader users understand the current state.

• Use aria-expanded to reflect the state of collapsible content.
• Ensure toggles are reachable via keyboard (e.g., Tab + Enter).
• Keep content in the DOM so assistive technologies can discover it.

How does the widget work?

The button toggles a hidden attribute on the content container. JavaScript updates the button label and aria-expanded value to keep the experience synchronized for assistive technologies.

Can I add animations?

Yes, you can animate opacity or transforms for smoother transitions. Be mindful of users who prefer reduced motion—respect the prefers-reduced-motion media query.
