This is the first example of an expand/collapse widget. Click the header above to toggle this content. The content can include text, lists, images, or any other HTML elements.
The animation provides a smooth expand/collapse effect using CSS transitions.
This widget is commonly used for FAQs, accordions, collapsible panels, and any content that needs to be hidden by default to save space and improve user experience.
The widget uses JavaScript to toggle a CSS class that controls the max-height property, creating a smooth animation effect. The transition is handled entirely with CSS for better performance.
Yes! You can easily customize the animation duration, colors, and behavior by modifying the CSS variables and JavaScript functions.
The implementation uses a simple onclick event handler that toggles the 'active' class on the parent container. This class then triggers the CSS transition on the .details element.
Note: The max-height value (500px) should be adjusted based on your maximum expected content height for optimal performance.
