How you can Management CSS Animations with JavaScript

Relating to animations on the net, builders must measure the animation’s necessities with the suitable expertise — CSS or JavaScript. Many animations are manageable with CSS however JavaScript will at all times present extra management. With doc.getAnimations, nonetheless, you should utilize JavaScript to handle CSS animations!

The doc.getAnimations methodology returns an array of CSSAnimation objects. CSSAnimation supplies a bunch of details about the animation: playState, timeline, impact, and occasions like onfinish. You may then modify these objects to regulate animations:

// Make all CSS animations on the web page twice as quick
doc.getAnimations().forEach((animation) => {
  animation.playbackRate *= 2;
});

// Cease all CSS animations on the web page
doc.getAnimations().forEach((animation) => {
  animation.cancel();
});

How may adjusting CSS animations on the fly be helpful to builders? Perhaps use the Battery API to cease all animations when the machine battery is low. Presumably to cease animations when the consumer has scrolled previous the animation itself.

I really like the way in which you should utilize JavaScript to change CSS animations. Builders used to want to decide on between CSS and JavaScript — now we’ve the instruments to make them work collectively!
