Creating Scroll Animations with Waypoints and Animate.css Last fall Atomic Object launched a redesigned website with lots of great new visuals and content. One of my favorite features of the redesign is the “slide-in reveal” homepage animation that slides images and text in from the sides of the screen as you scroll down the page. Bug 204882 - Add support for scroll behavior relies on ScrollAnimation of the Web process. Scroll-animation-in-web-process-for-review (98.20 KB, patch). Try using animated scroll effects in your next project! It’s a nice way to gently guide users to specific parts of your web page that they’ll surely appreciate 📜 Browser compatibility is solid across the board with the exclusion of Safari, however there's a popular polyfill available that will give you blanket coverage on major browsers.
