Carousel

[kair-uh-sel]

A carousel, also known as a slider or slideshow, is a web design component that displays multiple pieces of content in a rotating sequence within a single, contained area of a webpage. Users can typically navigate through the content manually using navigation arrows or indicator dots, while many carousels also rotate automatically at set intervals.

Common Uses of Carousels

Product Showcases

E-commerce websites frequently implement carousels to display multiple product images, allowing customers to view items from different angles or see various products in a collection. This application helps maximize space while maintaining an engaging shopping experience.

Featured Content

Many websites use carousels to highlight multiple important pieces of content, such as news articles, blog posts, or promotional offers. This allows organizations to showcase various messages without overwhelming the page layout.

Image Galleries

Photo-heavy websites often employ carousels as an interactive way to display image collections, giving users control over how they view and interact with the visual content.

Best Practices for Carousel Design
