They are just using a template. Yu-Gi-Oh! wiki has made their banner through CSS. Although both ways give nearly the same result (albeit the one with CSS follows the video even after you scroll down the page), they are not satisfactory as they take a part of the page.

If I end up not being able to make a notification for this purpose, I'll probably use one of these methods.
