How can I make width expand and collapse within a few seconds?

[Just_Jack 0 Likes (Newbie)]

Hello! Is there an easy way to make the width of a span expand to like 500px and then collapse to 0, within a few seconds? Here is what I have so far:

gsap.to('.block', {duration: 1, width: 500}, 0.2); 

I know when using keyframes it would be something like this:

@-webkit-keyframes block {
    0% {
        width: 0px
    }
  100% {
        width: 500px
    }
}

Thank you!

So you just want it to expand and then contract a few seconds later? Please try this.

 

gsap.to(".block", {
  duration: 1,
  width: 500,
  yoyo: true,
  repeat: 1,
  repeatDelay: 3
});

Is that what you meant?

 

Happy tweening.

Also keep in mind that width is not a performant property to animate. So if you can use scaleX or another way using performant properties (like overflow: hidden on a container and then animating the child's x property) it'd perform better.
