Expand/Collapse Widget Demo

This is a basic expand/collapse widget that shows and hides content when the header is clicked. The content is wrapped in a div with the 'details' class, which controls the visibility through CSS transitions.

The smooth animation makes the interaction feel polished and professional.

• Smooth CSS transitions for expand/collapse animations
• Click-to-toggle functionality using simple JavaScript
• Visual feedback with rotating arrow icon
• Accessible design with keyboard-friendly interactions
• Responsive layout that works on all devices
• Customizable styling through CSS classes

This widget can be easily integrated into any web application or website.

How it works:

CSS: The .details class uses max-height: 0 to hide content, and max-height: 500px when expanded. The transition property creates smooth animations.

JavaScript: The toggleDetails() function adds/removes the 'expanded' class to show/hide content.

HTML Structure: Each example is wrapped in a div with class 'example', and the collapsible content uses the 'details' class.

You can adjust the max-height value based on your content needs or use JavaScript to calculate the actual height for more precise control.
