JavaScript Scroll Animation Tutorial | Web Animations API + ScrollTimeline

Scroll-based animations used to be pretty hard and usually meant turning to a library. With the Web Animations API and ScrollTimeline, it's now surprisingly easy to do!

    You don't need the 'defer' attribute on a module script, because a module is deferred by default.

No matter how I configure the animation bounding offsets, either by element or by static css units, the animation timeline is based on the length of the page, NOT the offsets.'

    Hey KP! Just have a small suggestion : in many videos I’ve heard you describe inset as a shorthand for “top, bottom, left, and right”… which is true! Just a gentle suggestion to alter that habit to “top, right, bottom, left” as I hear your voice echoing when I set an inset so I set my values as “inset: top bottom left right;”. Us noobs are such snowflakes , and take so much literally; since the order of the values are t, r, b, l think it may be helpful to viewers to add that explicitly when you explain inset as a shorthand bc it doesn’t follow the same pattern as margin (unless it’s one or three values). That’s all, not criticism just a suggestion that may help in the future !

    For me there is some weird behavior using threshold or custom offsets. Whatever I set, the elements always refer to the whole page length like the scroll tracker with 0 to 100 percent. I can set it to 0 to 50 percent but I can't manage to make the image only animate while in the viewport. Anyone has an idea how to fix it?

    Unfortunately, the polyfill is not very well maintained. Its interface has already changed from what is in this video. But worse is that it has diverged from what the actual SPEC looks like now. So if you go with this polyfill, you will have to re-write your code later, which is not what anyone would really want. Plus, it seems that it also may break other libraries that you use for animations like TypeIt because it poorly re-implements existing browser APIs.

  • @KevinPowell

    @KevinPowell

    2 жыл бұрын

    Intersection Observers are awesome, but they are more about triggering something when an element enters the viewport. Like, you can add a class (or remove a class) when it enters the viewport, and that class comes with an animation. In this case, the animation is completely linked with the scroll position.
