animation

问题 I have decided to create a fade in animation effect using vanilla javascript. This is the code for my fade in effect: document.querySelector('.open-1_1').onclick = function() { document.getElementById('about-frame').style.display = 'block'; for (opacity = 0; opacity < 1.1; opacity = opacity + 0.1) { setTimeout(function(){document.getElementById('about').style.opacity = opacity;},100) } }; What I am trying to do is incrementally increasing the opacity of the #about div from 0 to 1 by running

问题 Pardon my ignorance, as I'm learning. I'm working on getting div s with the class of .entry to animate upon intersection with the Intersection Observer by adding the class of .entry-animation to them. I've never worked with selecting all elements and animating before. Upon the first intersection, all elements simultaneously animate. What am I doing wrong? Here's the demo: JSFiddle Here's the HTML : <div id="content-container"> <div class="content"> <div class="entry"> <h2> Title of Post 1 <

问题 Is there any built-in way to make the animation start when the element is in-view (for example, when we scroll to the element)? Framer Motion has mount animations section which says: When a component mounts, it'll automatically animate to the values in animate if they're different from those defined in style or initial So I couldn't really find a straight forward way to make the animation start when it comes into view. However, I reached the only option I see for now is using Animation

问题 I have a class that takes some coordinate and duration data. I want to use it to animate an svg . In more explicit terms, I want to use that data to change svg attributes over a time frame. I'm using a step function and requestAnimationFrame outside the class: function step(timestamp) { if (!start) start = timestamp var progress = timestamp - start; var currentX = parseInt(document.querySelector('#start').getAttribute('cx')); var moveX = distancePerFrame(circleMove.totalFrames(), circleMove

问题 I have star png image and I need to rotate the star using Flutter AnimationController and Transformer. I couldn't find any documents or example for image rotation animation. Any idea How to rotate an image using Flutter AnimationController and Transform? UPDATE: class _MyHomePageState extends State<MyHomePage> with TickerProviderStateMixin { AnimationController animationController; @override void initState() { super.initState(); animationController = new AnimationController( vsync: this,

问题 SwiftUI animations are typically driven by state, which is great, but sometimes you really want to trigger a temporary (often reversible) animation in response to some event. For example, I want to temporarily increase the size of a button when a it is tapped (both the increase and decrease in size should happen as a single animation when the button is released), but I haven't been able to figure this out. It can sort of be hacked together with transitions I think, but not very nicely. Also,
