Accessible Infinite Looping Lightbox

In this tutorial, I’ll show you how to enhance the native Webflow Lightbox with infinite looping navigation — so users can keep moving through the gallery in either direction without ever hitting a dead end. This setup works with both CMS-powered galleries and static Lightbox galleries, supports desktop and mobile, and most importantly, keeps the whole experience fully accessible for keyboard users and assistive technologies. We’ll break down the structure of the gallery, the custom attribute that powers the enhancement, and how the script makes the native Webflow Lightbox feel much more polished and production-ready. 👉 Watch on YouTube: https://youtu.be/4VvfHryupPk
