Expand/Collapse Widget Demo

HTML stands for HyperText Markup Language. It provides the structure of web pages by using elements and tags to denote headings, paragraphs, lists, links, images, and more.

An accessible toggle should provide:

• Keyboard operability (focusable and activated with Space/Enter)
• Appropriate ARIA attributes (aria-expanded on the control, aria-controls pointing to the controlled region)
• Clear visual state for expanded/collapsed

Keep content concise, provide a summary of what is revealed, and allow users to easily collapse sections they’ve opened. Consider keyboard and screen reader users in your design.

• Use a clear label on the toggle.
• Animate transitions gently for context.
• Ensure no content is inaccessible when collapsed.
