 Ooh, look at this fancy effect. Look at each of these little items getting their own little moment to animate in as I scroll in. I can't wait to show you this. I'm using scroll driven animations and it's all from CSS. It's only a few lines. Don't you love it when that happens? So here's all the CSS powering that. We have a key frame that's called slide fade in. Make sure that it slides and fades in a little bit. Then we make sure that we check the user's motion preference and if they have no preference we're good to do some slidey cool stuff. And here's where we work with scroll driven animations. We give each card a view timeline name which we're then able to use as the animation timeline. See how the same name is here? We're going to power that key frame animation based on the viewport intersection of each card and each card's size. And then we clamp the range of that to it's contain zero and contain 50%. And that's why we get this sort of animation that's not going across the whole scroll port but just as it creeps in and it slides in you can see every size of every element affects that particular result. I love these scroll driven animations are so cool.
