Lightbox
A lightbox is a fullscreen media overlay that enlarges an image, video, or embed above a dimmed page so the user can inspect it without navigating away. It opens from a thumbnail or link and returns focus to the trigger when dismissed.
The pattern is immersive media focus: use when one piece of visual content deserves the full viewport — with optional prev/next navigation through a gallery. Unlike a general-purpose dialog, a lightbox centers the media itself and keeps chrome minimal so the artwork stays primary.
Also known as
- Image modal — modal overlay dedicated to viewing photos or media at full size

Common use cases
Use a lightbox when the user needs to view media at full size while staying on the current page:
- Photo and art galleries — enlarge portfolio, product, or editorial images from a grid of thumbnails
- Product detail — zoom into high-resolution photos on e-commerce pages
- Social and news feeds — expand an inline image or video without a full navigation
- Document previews — show a page, diagram, or map at readable scale
- Mixed media sets — browse a sequence of images or clips with prev/next controls
Avoid a lightbox when the content is primarily text or forms (use a dialog or drawer), when users need to compare items side by side (use a grid or split layout), or when inline viewing is enough (use a simple zoom or expandable image). Do not trap users in autoplaying slideshows — keep navigation explicit and pauseable.
Single-image lightboxes open one asset with a close control and optional caption. Gallery lightboxes add previous/next navigation and a counter across a finite set. Minimal variants hide chrome until hover or focus; toolbar variants add zoom, download, or share actions when those tasks are common.
