Expand / Collapse Widget Demonstration

This area contains extra information that is hidden by default. It is controlled by the button above using aria attributes. Keyboard users can toggle it with Enter or Space while focused on the button.

Implementations should keep aria-expanded on the button and aria-hidden on this region in sync for assistive technologies.

• Fixed an issue causing slow load times on large projects.
• Improved accessibility of modal dialogs and toggle controls.
• Minor bug fixes and performance improvements.

Q: Can I include interactive elements inside?

A: Yes. You can place links, forms, or other controls inside the .details container. They remain focusable when visible.
