<br><br>
<div class="box"></div>

.box {
    width: 100px;
    height: 100px;

//alias for brevity 
const sb = showBox;

const hb = new TimelineMax({paused: true}); //hidebox

btn.addEventListener('click', function(){
	if(box.classList.contains('active') !== true) {
      sb.play();
    	sb.set(box, {opacity: 0, y: 0});
    	sb.fromTo(box, 0.5, {opacity: 0, y: 0}, {opacity: 1, y: 0});
        box.classList.add('active');
    }
    else if(box.classList.contains('active')) {
      hb.play();
    	hb.fromTo(box, 0.5, {opacity: 1, y: 0}, {opacity: 0, y: -100});
        box.classList.remove('active');
    }
});

 

New to the forum. I am looking to be able to show an element with one tweened animation and hide with a different animation by clicking the same button. In this case the show is a fade in and the hide is a fade out with a vertical translate. I tried by toggling the .active class and conditionally show or hide based on whether box has the class or not. I have only got it to work once (toggle on off for two clicks) and then it stops. Can someone tell me where i'm going wrong. I want to be able to keep this vanilla js, thanks.

Problem was your box was covering the buttons so subsequent clicks were not happening. You either change the z-index of the elements or change the order in html.

 

Also, you don't need to add your tweens in the timeline, it is going to add new tweens to your timelines on every single click. Using tweenmax or local timeline is enough in this scenario. I also tweaked your conditions as second if statement was unnecessary.

Perfect. Thank you very much Sahil. Very informative, It didn't even occur to me that the block was covering the button.
