Implementing cards stacking animation on scroll with Gsap and ScrollTrigger - javascript

I have a module where 3 cards stack on top of each other and then, on scroll, the cards will unstack one by one. See GIF of desired effect here.
I have tried to emulate the above effect using GSAP and ScrollTrigger, however, my animation is yielding undesirable results.
Here is my code so fare, to be viewed on +1200px screens:
$(function() {
gsap.registerPlugin(ScrollTrigger);
const container = document.querySelector(".cardStacking__cards");
const card = document.querySelector(".stackCard");
const cards = document.querySelectorAll(".stackCard");
const height = 510;
const timeline = gsap.timeline({
scrollTrigger: {
trigger: ".cardStacking__cards",
pin: true,
markers: true,
scrub: 1,
start: "bottom-=10% center",
end: "bottom top"
}
});
timeline.from(".stackCard", {
y: (index) => height * (cards.length - (index + 1)),
duration: (index) => 0.6 / (index + 1),
ease: "none",
stagger: (index) => 0.3 * (index),
});
});

.cardStacking .stackCard {

margin-bottom: 50px;
padding: 106px 135px 126px 77px;

}
.cardStacking .stackCard:first-child {
box-shadow: 0px 10px 30px 0px rgba(0, 0, 0, 0.16);
}

Issue(s)
From the demo you can see that, as soon as the "scroller start" indicator scrolls to and past the "start" indicator, the cards disappear. Upon inspecting the code, for some reason, when the indicators pass, cardStacking__cards has a top value of top: -1334.52px, which I'm unsure why.
The section does not pin when the cards are in view. I'm trying to pin the section until all cards are revealed, and then unpin.


You can do it as below. I created a simplified version of the code you pasted to showcase the feature. Here is a codepen of it as well.
gsap.registerPlugin(ScrollTrigger);
const tl = gsap.timeline({
scrollTrigger: {
trigger: ".cards",
pin: true,
start: "top 10%",
end: "bottom+=1000 bottom",
scrub: true
}
});
tl.to(".first", {
y: "-90vh"
}).to(
".second",
{
y: "-85vh"
},
"-=0.15"
);
body {
text-align: center;
}
.cards {
position: relative;
height: 85vh;
}
.card {
border-radius: 2rem;
position: absolute;
inset: 0;
}
.first {
background: lightblue;
bottom: 10vh;
}
.second {
background: lightgreen;
bottom: 5vh;
}
.third {
background: lightgray;
}

Please take a look at working example https://jsfiddle.net/23dz0evy/4/. By modifying const bottom = 40 bottom margin between panels can be changed, works with infinite number of panels.

I would need something like this:
http://www.laurelhalo.com/
The main area should keep its width while hovering one of the two sidebars, and push off on one side. There also should be a sliding animation, like in the example.
How is it possible to realize that? Is it possible with jQuery?
Would be very thankful for help. :)

Just add min-width:100%; to your main-area class.
$(".left-area").mouseenter(function() {
$(".left-area-content").show();
$(".left-area-content-preview").hide();
}).mouseleave(function() {
$(".left-area-content").hide();
$(".left-area-content-preview").show();
});
$(".right-area").mouseenter(function() {
$(".right-area-content").show();
$(".right-area-content-preview").hide();

Bootstrap 4 sticky-top change Navbar color

To get a sticky navbar I used the Bootstrap 4 class sticky-top. I prefer the css solution instead of some JS, because that made some errors in the past.
I want to have my navbar in a transparent color when the user reaches it. (The moment my navbar gets sticky - that works). Before that it should have a random color. (That does not work - The grey background emerges from the transparent background of the sticky-top class).
I have not found a good solution to get this yet. I have tried to add a new class via JS, but that did not work.
Codepen example
/* Open tabs */
function openTab(evt, parameter) {
var i, tabcontent, tablinks;
tabcontent = document.getElementsByClassName("tabcontent");
for (i = 0; i < tabcontent.length; i++) {
tabcontent[i].style.display = "none";
}
tablinks = document.getElementsByClassName("tablinks");
for (i = 0; i < tablinks.length; i++) {
tablinks[i].className = tablinks[i].className.replace(" active", "");
}
document.getElementById(parameter).style.display = "block";
evt.currentTarget.className += " active";
}
/* Open tabs END */
/* Smooth scroll */
//Only where the class smooth-scroll is, scrolling is enabled
$(document).ready(function () {
$('a.smooth-scroll[href*="#"]:not([href="#three"])').click(function () {
if (location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '') && location.hostname == this.hostname) {
var target = $(this.hash);
//Comment the following line if you don't want to see the anchor in the url
//target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
if (target.length) {
$('html, body').animate({
scrollTop: target.offset().top
}, 1000);
return false;
}
}
});
});
/* Smooth scroll END */

For reasons explained here position:sticky (Bootstrap sticky-top) doesn't provide an indication of when it's "stuck".
Therefore, you need to use JS to conditionally change the Navbar color/style.
One way is using an IntersectionObserver. You can use this on the #nav-anker which is the element immediately before the sticky-top Navbar.
(new IntersectionObserver(function(e,o){
if (e[0].intersectionRatio > 0){
document.documentElement.removeAttribute('class');
} else {
document.documentElement.setAttribute('class','stuck');
};
})).observe(document.querySelector('#nav-anker'));
So when the Navbar becomes sticky, the stuck class is added to it. You can have CSS styles that change when it's stuck...
/* style for when sticky is applied */
.stuck .sticky-top {
background: #000;
}
Demo: https://www.codeply.com/go/psiFbB6Ro6

You can simply override the color of all "nav" styles.
Even tho it's not recommended to use "!important", this will work here.
Otherwise you will need to set up the style of all parents till the nav bar ancestor or pass an ID to the nav bar.
EDIT: By checking the offset of the element to the topside (which is 0 if it is sticky) you can change the opacity to whatever value you want.
So if the offset to top is 0 you lower the opacity and if the offset is greater than 0 you simply revert the opacity back to 1.

Too much text for overflow:hidden

I have a quite complex div layout.
It works on Safari and Firefox without any problem:
But opening the page on chrome gives me the following result:
So the whole screen is divided into two big divs that are placed vertically. The one at the top with the orange dots and the other one at the bottom with the colorful divs inside.
When I add too much text to the pink div the layout starts expanding itself.
The interesting thing is that the div is gets more text than it could show and it really works because of
overflow: hidden;
But starting at a quite high number of lines the div starts expanding itself for some reason
I was trying to reproduce the issue in fiddle.
But I am not able to.
What else could I try to find the problem?
Or does anyone see the mistake I did?
The code I give is for the half at the bottom were the problem probably is.

Justify paragraphs by changing the word-spacing

Is there a smart way to justify paragraphs inside a fixed-width div tag without wrapping and only changing the word-spacing? See link below.

Making Sidebar with bootstrap3

I wanna make sidebar like this http://dota2.cyborgmatt.com/prizetracker/dotapits3
but couldn't do it. Everytime I tried and failed. You can click to sidebar text and it can open to you at right side section.
I'm new kinda things thank you.

I created a sidebar for bootstrap, because i didn't find what i searched for on internet, here's the code
CSS
#wrapper {
margin-left: 200px;
}
#sidebar-wrapper {
width: 200px;
background: #555;
height: 100%;
position: fixed;
left: 0;
top: 0;
}
#sidebar-wrapper .logo {
text-transform: uppercase;
color: #FFF;
text-align: center;
padding: 15px 0;
font-size: 36px;
font-weight: bold;
border-bottom: 1px solid #666;
}
#sidebar-wrapper .nav.nav-pills.nav-stacked {
margin-top: 30px;
}
#sidebar-wrapper .nav.nav-pills.nav-stacked li {
}
#sidebar-wrapper .nav.nav-pills.nav-stacked li a {
color: #FFF;
}
#sidebar-wrapper .nav.nav-pills.nav-stacked li a:hover {
background: #333;
}
**HTML**
<div id="sidebar-wrapper">
<div class="logo">
LOGO
</div>
<ul class="nav nav-pills nav-stacked">
<li><span class="glyphicon glyphicon-th-list"></span> Produits</li>
<li><span class="glyphicon glyphicon-user"></span> Clients</li>
<li><span class="glyphicon glyphicon-calendar"></span> Réservations</li>
<li><span class="glyphicon glyphicon-shopping-cart"></span> Commandes</li>
<li><span class="glyphicon glyphicon-envelope"></span> Messages</li>
</ul>
</div>
Here's an example of the result in this Bootply

If you're already using Bootstrap you can use the baked in components. Take a look at http://getbootstrap.com/components/#nav and you are ready to go. Also you can analyze the code used in your example and look up how it's done. It's pretty straightforward.
EDIT: I fiddled something: http://jsfiddle.net/Ltyuxy7h/6/
<div class="row">
<div class="col-xs-2">
<ul class="nav>
<li>Testlink</li>
<li>Testlink</li>
<li>Testlink</li>
<li>Testlink</li>
<li>Testlink</li>
<li>Testlink</li>
</ul>
</div>
<div class="col-xs-10">
