Hey guys, I am happy to be here and use your amazing tools for my upcoming personal website. That being said, I need your advice. What would you say would be best practices when dealing with multiple reveal animations on scrolling? I've found that mobile performance (on Chrome, since Firefox seems to perform beautifully) is pretty bad when it comes to the way my reveal animations trigger. They feel stuttery and somewhat low-fps. I've tried slowly scrolling to avoid overriding them by dragging the screen (to see if multiple animations firing at once could be the cause), but the choppy animation effect is pretty much the same even if only one animation triggers. For reference, I've set up my reveal animations using attributes. I place certain attributes on certain elements, and a switch statement detects the type of animation that needs to be fired for each element. Here's more or less how this code is setup. Maybe you have some pointers on how would be best to setup something like this? function loadGSAPAnimations() { let selector = "[data-reveal]"; // Base selector for elements to animate // Query the DOM once for each modified selector let itemsToAnimate = document.querySelectorAll(selector); itemsToAnimate.forEach((itemFound) => { const elementTimeline = gsap.timeline({ delay: itemFound.dataset.delay || 0, // If "data-delay" attribute is present, adjust value defaults: { duration: 1, ease: "power4.out" }, }), animationType = itemFound.dataset.reveal; switch (animationType) { case "multi-element-reveal": const childElements = itemFound.querySelectorAll(childSelector); gsap.set(childElements, { opacity: 0, y: 115, willChange: "transform, translateY", }); elementTimeline.to( childElements, { opacity: 1, y: 0, stagger: 0.2, ease: "power4.out", onComplete: () => { gsap.set(childElements, { willChange: "auto" }); }, }, "+=0.3" ); break; case "element-reveal": gsap.set(itemFound, { opacity: 0, y: 115, willChange: "transform, translateY", }); elementTimeline.to( itemFound, { opacity: 1, y: 0, duration: 1, ease: "power4.out", stagger: 0.15, onComplete: () => { gsap.set(itemFound, { willChange: "auto" }); }, }, "+=0.3" ); break; case "title-reveal": let elementText = new SplitType(itemFound, { types: "lines", lineClass: "title-line", tagName: "span", }); gsap.set(elementText.lines, { opacity: 0, y: 115, willChange: "transform, translateY", }); elementTimeline.to( elementText.lines, { opacity: 1, y: 0, duration: 1, stagger: 0.15, ease: "power4.out", onComplete: () => { gsap.set(elementText.lines, { willChange: "auto" }); elementText.revert(); }, }, "+=0.3" ); break; case "image-reveal": const image = itemFound.querySelector("img"); const innerWrapper = image.closest(".image-animation-wrapper"); gsap.set(innerWrapper, { scale: 1.15, "--reveal-scale": 1, force3D: true, willChange: "scale, transform, translateY", }); elementTimeline.to( innerWrapper, { "--reveal-scale": 0, scale: 1, duration: 1.5, ease: "power4.out", onComplete: () => { gsap.set(innerWrapper, { willChange: "auto" }); }, }, "+=0.3" ); break; } //Controls the distance from the screen when the item gets revealed on scroll const revealOffset = itemFound.dataset.offset || 84; // Create the ScrollTrigger instance ScrollTrigger.create({ trigger: itemFound, animation: elementTimeline, start: `top ${revealOffset}%`, end: "bottom 35%", refreshPriority: -1, }); }); }

GSAP noob over here... and loving it so much! I was just wondering if anyone has established beautify setups to share? I've grown accustomed to using the order of CSS properties I stole from Bootstrap and the OCD in me is itching for something similar in GSAP. eg for CSS order of properties: 1) Positons (absolute, top, left, z-index etc) 2) Box-model (block, padding, margin, etc) 3) Layout (flex & grid type of stuff) And so on... It's worth noting for CSS I just used a feature in PHPStorm that allows you to create a list of the order you want. So I'm not sure if the same will be possible with GSAP. I guess I'm just asking out of interest for the most part.

So, can I deliver banner files gzipped? I have an ad that we converted with Swiffy; it looks amazing, and right there, in the Swiffy output window, it shows the file size of the banner as 88k -- but it's the gzipped file size. The raw file size of the html when I download it, is 346k. I'm pretty sure I can use gzipped files in Doubleclick, but what about other media people/publishers? Anyone have experience with this?
