Ever tried to get a Fancybox YouTube modal working on your test page, only for it to fail on `localhost`? In this video, we walk through the process of setting up a clean video modal popup for both YouTube and Vimeo, and then troubleshoot why it might not work in a local development environment.

We'll cover grabbing the necessary CDN links for jQuery and Fancybox, structuring the HTML with the correct `data-fancybox` attributes, and customizing the embed URL parameters for things like autoplay and controls. Follow along as we debug the common pitfalls and compare a non-working local example with a fully functional one on a live server.
