In this tutorial, we are going to make accordion using HTML, CSS, and jQuery.
The accordion is a vertically stacked list of items. Each item can be “expanded” or “collapsed” to reveal the content associated with that item. There can be zero expanded items, exactly one, or more than one item expanded at a time, depending on the configuration.
Accordions are popular because they allow developers to force large amounts of content into tiny spaces on the page.
