Lightbox modals magnify images or videos in an overlay that covers the whole screen. Triggered by clicking an image or button, they often come with features like navigation controls, captions, and zoom options.

A significant perk of using a lightbox modal is that it lets users focus on the content without steering away from the main page. This is great for times when users want a closer look at a photo or video but don't want to lose their spot on the site or app. Lightboxes are especially popular in designs that are rich in photos and videos, as they offer a cinematic viewing experience.
