Mastering GSAP Interactions in Webflow: Accessible Sidebar with Scroll Lock & Focus Trap

In this lesson of the Mastering GSAP Interactions in Webflow series, we’re building a fully functional and accessible sidebar system — powered by Webflow’s GSAP interactions. You’ll learn how to connect each card in a CMS collection to its own sidebar, animate it smoothly into view, and lock the page scroll while it’s open. But more importantly, we’ll go beyond visuals. We’ll make sure the entire experience is properly accessible — with semantic HTML buttons, ARIA attributes, keyboard navigation, focus management, and a simple JavaScript layer to tie everything together. By the end of this video, you won’t just have a nice-looking sidebar — you’ll have a system that behaves the way it should. 👉 Watch on YouTube: https://youtu.be/fC96W2pDQCM
