CSS accordion uses :checked hack for collapsible sections.

Introduction to CSS Accordion

A CSS accordion allows sections of content to expand or collapse when clicked. This is achieved using the :checked pseudo-class in combination with hidden HTML checkboxes. The accordion effect is commonly used for FAQs, menus, and more.

Basic Structure of a CSS Accordion

The basic structure of a CSS accordion consists of a checkbox, a label, and a content section for each accordion item. The checkbox is hidden and used to track the state of the accordion (expanded or collapsed).

Styling the Accordion with CSS

Using CSS, we can style the accordion to hide the content by default and display it when the associated checkbox is checked. The + adjacent sibling selector is useful for this purpose.

Adding Animation for Smooth Transition

To make the transition smoother when the accordion expands or collapses, you can add a transition effect. Modify the max-height property in the CSS for a smoother animation.

Conclusion

CSS accordions offer a simple and effective way to organize content in a collapsible format. By utilizing the :checked pseudo-class and hidden checkboxes, you can create dynamic interfaces without JavaScript. Experiment with different styles and settings to suit your project's needs.
