Custom horizontal scroll with animate.css

Question

I have some code:

$(window).load(function(){
	// Horizontal scroll
    if($(".js-page-scroll").length){
        $(".js-page-scroll").mCustomScrollbar({
        	axis:"x",
            theme:"dark-3",
            // scrollbarPosition: 'outside',
            advanced:{ autoExpandHorizontalScroll:true },

            callbacks:{
                    whileScrolling:function(){
                    	
                    	new WOW().init();
                        
                    }
                }
        });
    }
});

main {
    display: flex;
    flex-flow: row nowrap;
    align-items: center;
    align-content: center;
    justify-content: space-between;
}

section {
    display: block;
    width: 300px;
    border: 1px solid #000;
    padding: 1rem;
}

.js-page-scroll {
    width: 100%;
    overflow-x: auto;
}

I use custom scroll (horizontal) - malihu custom scrollbar

For animation - animate.css and wow.js

The problem is that with the horizontal scroll, the text in the blocks appeared (animated) smoothly and, consequently, sequentially (as when using wow.js).

Question: how to configure wow.js (or, perhaps, what is another plugin) for a horizontal scroll? or How to configure animate.css for a custom scroll (when scrolling blocks appear smoothly, sequentially)?

Answer 1

In your snippet, the issue is you have initiated the WOW plugin on the scrolling. That's why the animation for all paragraph tag is triggered simultaneously.

From your snippet, I have added custom code instead of using WOW Plugin. While scrolling I have called custom function added by me animateContent();

JS CODE

// Custome code for smooth animation 

                  function animateContent() {

                   var divWidth = $(".js-page-scroll").width();
                   var divWidthLg = $(".js-page-scroll").width() - 20;
                   var divWidthMd = $(".js-page-scroll").width() - 40;
                   var divWidthSm = $(".js-page-scroll").width() - 100;
                        //console.log(divWidth);
                         //console.log(divWidthLg);console.log(divWidthMd);


                    var section =$("section");


                     section.each(function(){


                     var offset = $(this).offset().left;
                     var ind = $(this).index() + 1;

                    // console.log(ind, offset);

                     if(offset > divWidth) {
                         $("p" , this).addClass("animated fadeOutUp");

                      }

                     if ( (offset < divWidthLg)){

                     if ($("p" , this).hasClass("fadeOutUp")){
                     $("p" , this).removeClass("fadeOutUp");
                     $("p" , this).addClass("animated fadeInUp");
                     setTimeout(function(){
                     $("p" , this).removeClass("fadeInUp");
                     }, 1500);
                     }
                     else {
                     $("p" , this).addClass("animated fadeInUp");
                     }

                     }

                     if(offset < divWidthSm) {
                      // $("p" , this).removeClass("fadeOutUp");
                       // $("p" , this).removeClass("fadeInUp");
                     }

                     });

                }

What I have done:

• At first, I have found the total width of the outer div
• Then next to it I have found the offset position of each section
• If the offset position is less then the total width of outer div and the right offset position, I added animated fadeInUp class thats it.

Here is the demo in Fiddle.

UPDATE (Seperate animation for each element)

Here I have attached the Fiddle demo link.

What I have done here: I just get the animation IN and OUT class form data attribute, and append the required animation when it necessary.

By this you can handle IN and OUT animation for each section.

$(window).ready(function(){
    	// Horizontal scroll
        if($(".js-page-scroll").length){
            $(".js-page-scroll").mCustomScrollbar({
            	axis:"x",
                theme:"dark-3",
                // scrollbarPosition: 'outside',
                advanced:{ autoExpandHorizontalScroll:true },

                callbacks:{
                        whileScrolling:function(){
                     animateContent();
                        }
                    }
            });
        }
    });
                //	new WOW().init();
                
                function animateContent() {
                
              
                
                   var divWidth = $(".js-page-scroll").width();
                   var divWidthLg = $(".js-page-scroll").width() - 20;
                   var divWidthMd = $(".js-page-scroll").width() - 40;
                   var divWidthSm = $(".js-page-scroll").width() - 100;
                        //console.log(divWidth);
                         //console.log(divWidthLg);console.log(divWidthMd);

                     section.each(function(){
                     
                 			var inAnimation = $("p" , this).data("inanimation");
                     var outAnimation = $("p" , this).data("outanimation");
                     var offset = $(this).offset().left;
                     var ind = $(this).index() + 1;
                     
 						// console.log(ind, offset, inAnimation, outAnimation);
