CSS Animations Not Visible on Mobile

Site URL: http://www.ballybrookfarm.com/home

Thanks in advance for any help! 

I've loaded an css animation library to my site, added the correct codes as instructed, and the animations work fine on desktop version. However, when I view on a mobile device, each animation is hidden. I've searched for an answer and am not coming up with any solution. 

Here is the website link: www.ballybrookfarm.com/home

Here is the code I am using in the code block:

<div id="#block-yui_3_17_2_6_1459644649106_53673" class="slideUp">
 <script> 
 $(window).scroll(function () {
 $('#block-yui_3_17_2_6_1459644649106_53673').each(function () {
 var topOfWindow = $(window).scrollTop(),
 bottomOfWindow = topOfWindow + $(window).height();
 
 var imagePos = $(this).offset().top;
 
 if(imagePos <= bottomOfWindow-250 && imagePos >= topOfWindow+250){
 $(this).addClass('slideUp');
 }
 //else{
 //$(this).removeClass('slideUp');
 //}
 });
 });
 </script>

And this is the code I am adding to the Custom CSS section:

#block-yui_3_17_2_6_1459644649106_53673{
background-color: #ffffff;
visibility: hidden;
}

Hoping to have the exact same animations seen on desktop on a mobile device.

Thank you!
