Is it possible to improve the performance of CSS animation by preventing it from running when the animated object is not visible on the viewport? Thank you!
Is it possible to improve the performance of CSS animation by preventing it from running when the animated object is not visible on the viewport? Thank you!
To implement a smooth animation effect when an object enters the viewport, you can dynamically add or remove a CSS class with animation properties. Here's an example code snippet:
// Define the CSS class for the animation
.animationClass {
animation: someAnimation 5s;
-moz-animation: someAnimation 5s; /* Firefox */
-webkit-animation: someAnimation 5s; /* Safari and Chrome */
-o-animation: someAnimation 5s; /* Opera */
}
// jQuery code to trigger animation when object is in view
if (isObjectInViewPort() == true) {
$('.someObject').addClass('animationClass');
// You can also remove the class using $('.someObject').removeClass('animationClass');
}
It can be challenging to determine when the object leaves the viewport. Constantly checking this may not be efficient as CSS animations are usually lightweight and perform well. It's essential to balance performance and visual effects when implementing animations.
