A carousel is a graphical user interface component that displays multiple items in a rotating fashion, usually through a series of images or slides. The items are usually displayed one at a time, and users can navigate through the items using buttons or swipe gestures.
In web design, carousels are used to display multiple pieces of content or images in a compact and visually appealing way, without taking up too much space on the page. They are particularly useful for showcasing products, images, articles, or other types of content in a dynamic and interactive manner. By using a carousel, designers can provide a way to highlight multiple pieces of content and encourage users to interact and explore further. Additionally, carousels are also useful for improving the accessibility of the site, as they allow users to easily navigate through the items and access the information they need.
