Expand/Collapse Widget Demo

HTML (HyperText Markup Language) is the standard markup language used to create web pages. It provides the structure and content of websites by using a system of tags and attributes. HTML works alongside CSS for styling and JavaScript for interactivity.

  • Smooth expand/collapse animations
  • Responsive design
  • Accessible button controls
  • Visual feedback on hover
  • Rotating arrow indicator
  • Easy to customize styling

Click the button above to expand or collapse the content. The widget uses CSS transitions to create a smooth animation effect. The arrow rotates 180 degrees when expanded, and the details section slides open and closed with a maximum-height transition.

Each widget is independent, so you can expand multiple sections at the same time.

Can I have multiple sections open?

Yes! Each toggle operates independently, so you can expand as many sections as you want simultaneously.

Is this mobile-friendly?

Absolutely! The widget is fully responsive and works great on mobile, tablet, and desktop devices.
