Fade Images on Scroll with Javascript (Intersection Observer Part 2)
In my last video ( • Transparent Nav to Background Color N... ), I looked at the Intersection Observer API in Javascript for changing a transparent nav to a background-color nav. In this video, I'll show you how to fade images in on scroll with some simple vanilla Javascript. The intersection observer is more performant because it doesn’t have to watch every moment you’re scroll. You tell it what to watch and it’ll observe (almost like a click event listener) and run only when necessary.

• set up an intersection observer
• add or remove classes when the observed element is in the window (or out of the window)
• use the observer threshold in the options object
• run intersection observers on multiple elements
• and more!
