If you're looking to spice up a webpage without slowing it down too much. think twice before using CSS animations on every element!
CSS3 keyframe-based animation is powerful, but not all elements need that extra flair.
>Imagine: Every button pulsing gently as if alive.>>That's 10ms wasted per frame across multiple buttons.Instead:
- Use
JavaScript for dynamic effects only
Avoid overusing CSS animations
// Example of lazy loading animation on scroll using Intersection Observer APIconst observer = newIntersectionObserver((entries) => {entries. forEach(entry=>if (entry. isIntersecting)entry. target. style. animationName="fadeIn";});observer. observe(yourElement);Less is more. Stick to key elements that benefit the most from animation.
