Hello,
I use this script wich works fine on laptop bur i just see that it doesn’t works on mobiles:
```
<script>
function scrollTrigger(selector, options = {}){
    let els = document.querySelectorAll(selector)
    els = Array.from(els)
    els.forEach(el => {
        addObserver(el, options)
    })
}

function addObserver(el, options){
    if(!('IntersectionObserver' in window)){
        if(options.cb){
            options.cb(el)
        }else{
            entry.target.classList.add('active')
        }
        return
    }
    let observer = new IntersectionObserver((entries, observer) => { //this takes a callback function which receives two arguments: the elemts list and the observer instance
        entries.forEach(entry => {
            if(entry.isIntersecting){
                if(options.cb){
                    options.cb(el)
                }else{
                    entry.target.classList.add('active')
                }
                observer.unobserve(entry.target)
            }
        })
    }, options)
    observer.observe(el)
}
// Example usages:
scrollTrigger('.intro-text')

scrollTrigger('.scroll-reveal', {
    rootMargin: '-200px',
})

scrollTrigger('.loader', {
    rootMargin: '-200px',
    cb: function(el){
        el.innerText = 'Loading...'
        setTimeout(() => {
            el.innerText = 'Task Complete!'
        }, 1000)
    }
})
</script>
```
I use it for an animation on this page: https://vernissageduvar.com/

Is it normal? is it a solution to make it working?

Thanks!!

Hello,
On phone i did it wittout this script… the animation doesn’t start like on lapetop when you arrive to the élement but it strats when the page is load….because his script doesn’t works on mobile…

Hi,

Thank you for the inquiry.

How did you create the animation? You may need to set the opacity of the elements with the class name “scroll-reveal” to zero to make them invisible on initial load. Once the elements are scrolled into view, the script above should add the “active” class name to the element, which can be used to reset the opacity back to 1, making the elements visible. However, please note that the script above might not be able to control when the animation starts
```
.scroll-reveal { 
  opacity: 0;
}

.scroll-reveal.active {
  opacity: 1;
}
```
Best regards,
Ismael

the section itself is set to : av-small-hide av-mini-hide.
those flex_columns with .scroll-reveal trigger are set on visibility : av-hide-on-mobile
look at the column advanced tab under responsive. Your added Class could not work on that – because it is set to display : none by your responsive settings.

is it because you are working with the other option to show that animation?

if this section and the columns are set to be there on responsive case the class “active” is added.

_____________________

by the way – this is my observer sccript to get a new class added to flex-columns that comes into viewport.
( i do not stop observing, because i like the animation on scroll-in/out again and again ;)
```
function observe_columns() {
?>
<script type="text/javascript">	
	document.addEventListener("DOMContentLoaded", function() {
	  var flexcolumns = [].slice.call(document.querySelectorAll(".flex_column"));
		
		if ("IntersectionObserver" in window && "IntersectionObserverEntry" in window && "intersectionRatio" in window.IntersectionObserverEntry.prototype){
			let flexcolumnObserver = new IntersectionObserver(function(entries, observer) {
				entries.forEach(function(entry) {
					if (entry.isIntersecting) {
						entry.target.classList.add("visible");

					}
					else {
						entry.target.classList.remove("visible");
					}  
				});

			}, {
				root: null,
				threshold: 0.1,
				rootMargin: "20px 0px -10px 0px",
			});
			
			flexcolumns.forEach(function(flexcolumn) {
				flexcolumnObserver.observe(flexcolumn);
			});
	  	}
	});
</script>
<?php
}
add_action( 'wp_footer', 'observe_columns' );
```
see in action f.e. under “Dienstleistungen”
