Lightbox

Full-screen image and video viewer with zoom, keyboard navigation, fullscreen, download, share, thumbnails, and a slide counter. Highly slot-driven for custom chrome.

Default

Pass an array of images and render thumbnails that open the lightbox.

Custom trigger

Use the #trigger scoped slot to open the lightbox from any element. Receives { open, openAt, items }.

Mixed image + video

Items can be images or { type: 'video', src, poster }. Videos auto-pause on slide change.

Minimal chrome

Hide the thumbnail strip, counter, and download button for a bare viewer.
