Expand/Collapse Widgets

Native HTML <details>
Click to expand

This is a native HTML details element. It provides built-in expand/collapse functionality without requiring any JavaScript. The browser handles the open and closed states automatically.

You can style the summary and details content with CSS to match your design requirements.

Custom JavaScript Toggle

This is a custom expand/collapse widget built with JavaScript. It provides more control over the animation and appearance.

The toggle state is managed by adding and removing the 'active' class, allowing for custom animations and styling.
