I'm having trouble with 'Collapse' and 'Expand All' functionality:
The 'Expand All' button isn't working. How do I fix this code?
When I do Collapse each item individually the red and purple boxes (around them) do not expand accordingly (if the text exceeds the pre-set height). The Collapse items also spill over and go all the way down the page and over the footer. How do I get the red and purple box to expand with the text IF the max length of the text goes further down past the end of their height?
//Expand All
function toggleAll() {
var buttons = Array.prototype.slice.call(document.querySelectorAll('.testingpol_extrainfo_column'));
buttons.forEach(function(button) {
//Swap each element between display 'none' and 'block'
if (window.toggleAll === 0) {
button.style.display = 'block';
} else {
button.style.display = 'none';
}
// Swap window.toggleAll between 0 and 1
window.toggleAll = window.toggleAll === 0 ? 1 : 0;
});
}
// Collapse Individual points
var coll = document.getElementsByClassName("testingpol_extrainfo_column");
var i;
for (i = 0; i < coll.length; i++) {
coll[i].addEventListener("click", function() {
this.classList.toggle("active");
var content = this.nextElementSibling;
if (content.style.display === "block") {
content.style.display = "none";
} else {
content.style.display = "block";
}
});
}

I rewrote all of your JS and added min-height and flexbox properties to your banner and outerbackground as flexbox will flex with the content. I reworked the JS with a .show class and toggled that class. Hope this is what you are looking for.
//Expand All
const expandAll = document.getElementById('expandAll');
expandAll.addEventListener('click', () => {
// const buttons = document.querySelectorAll('.testingpol_extrainfo_column');
const content = document.querySelectorAll(".testingpol_extrainfo_content");
for (let i=0; i < content.length; i++) {
content[i].classList.remove('show-individual');
content[i].classList.toggle('show');
}
});
// Collapse Individual points
const banner = document.querySelector('.testingpol_extrainfo_banner');
banner.addEventListener('click', (e) =>{
const col = document.querySelectorAll(".testingpol_extrainfo_column");
const content = document.querySelectorAll(".testingpol_extrainfo_content");
for (let i=0; i < col.length; i++){
if (e.target === col[i]){
content[i].classList.toggle('show-individual');
}

I create an effect that is to constantly display the image while scrolling text. I have a question how to make it work the same way, instead of position: sticky, posititon: fixed, so that this effect works on ie.
var sticky = document.querySelector('.sticky-container');
var img = document.querySelector('.sticky-item');
window.addEventListener('scroll',setSticky);
function setSticky(){
var top = sticky.offsetTop - window.pageYOffset;
if(top <= 0){
sticky.classList.add('sticky');
}
if(top.toString().replace('-','') >= sticky.offsetHeight || top >= 0){
sticky.classList.remove('sticky');
}
};

Dai is correct, you do not need to use a script to achieve this effect.
https://jsfiddle.net/tractionworks/h3r5uvqm/8/
Since you need to use the position:sticky feature I doubt this works on IE without a big effort and actually using JS. But with 1.4% global usage I doubt this is worth your time.
However if you are fine with the coverage of sticky, I would entirely skip using JS and solve it via CSS:
* {
margin: 0;
}
body {
width: 100%;
padding: 120vh 0;
}
p {
font-size: 28px;
color: #fff;

margin: 80px 0;
}
.sticky-item {
position: sticky;
top: 0;
z-index: -1;
width: 100%;
height: 100vh;
background: url(https://www.apple.com/v/iphone-xs/a/images/overview/camera_hero_large.jpg) center / cover no-repeat;

i want to hide a single div at a time so that below flashing can be avoided(shown in image)
NOTE: i cannot use visibility:hidden or visibility:show or $sel.css('visibility','hidden'); or $sel.css('visibility','show');
My Expectation: when I do $content.hide(); in the DOM see html area in image provided by me where style="display:none"/style="display:block" is happening for every element, rather I want to hide that particular element at a time (so no multiple display/hide at a time, only one display/hide) similar to #snippet2, #snippet1 should work (but hidden element should not contain any width/height)
below is my code which should work with display:none or $el.hide()/$el.show():
#Snippet1
$(function() {
var pos = 1;
var ii = 0;
var centerbandTop = $('.center-band').offset().top;
var centerbandBottom = $('.center-band').outerHeight() + centerbandTop;
$('.contents').hide();
var intId = setInterval(function() {
ii++;
pos = -ii;
//console.log(pos);
//if (pos )
$('.contents').each(function() {
var $content = $(this);
var contentTop = $content.offset().top;
var contentBottom = $content.outerHeight() + contentTop;

Please help me thanks in advance!!!
It is hard to understand your question, but from the code snippets you provided it looks like you need to fundamentally rethink your approach.
Your code moves the "container" div up and then computes the positions of the contained elements, but the problem is that when you hide or show an element all the other elements move in response. So when "contents 1" gets above the center band and you hide it, it stops taking up space and "contents 2" moves to where "contents 1" was. However, since "contents 1" was above the center band, now "contents 2" is above the center band and you are going to hide that, too. And so in your code, as soon as "contents 1" gets above the center band, all the contents will be hidden.
There are many ways to handle this, and the best way for your situation will probably depend on details of what you are truly trying to accomplish and which are not clear from your question. Using CSS overflow: hidden is probably the most efficient and you do not really explain what is wrong with that solution.
Another option is to adjust the position of the container to compensate for hiding the element. You also have to have some way to figure out when to show items that enter the box, which you cannot do from their position, because they are hidden. This snippet is not ideal, and there are some glitches because of margins, but it shows the concept.
$(function() {
var pos = 0;
var showNext = false;
var centerbandTop = $('.center-band').offset().top;
var centerbandBottom = $('.center-band').outerHeight() + centerbandTop;
var scroll = function() {
pos--; // move the list up one pixel
$('.contents').each(function() {
var $content = $(this);
// If the previous "contents" moved up enough
// to make room for this hidden element, show it.
if (showNext) {
$content.show();
showNext = false;
} else if ($content.is(':hidden')) // nothing to do
return;
// We have to wait until after we have shown
// the element to compute its position.
var contentTop = $content.offset().top;
var contentBottom = $content.outerHeight() + contentTop;
if (contentBottom < centerbandTop) {
// If the element has exited the top of the
// band, hide it, and move the container
// down to compensate for removing this
// element.
pos = pos + $content.outerHeight(true);
$content.hide();
} else if (contentTop > centerbandBottom) {
// If the element is below the band,
// hide it. Really this only needs to
// be done the first time through.
$content.hide();
}
// If there is room in the center band
// below this element, show the next one
showNext = contentBottom < centerbandBottom;
$('.container').css({
transform: 'translateY(' + pos + 'px)'
});
});
}
// We start with the contents "visibility: hidden"
// and all the elements displayed so we do not
// see them but still can compute their positions.
// One pass through scroll() then hides everything
// that needs to be hidden.
scroll();
// Now we can make everthing visible
$('.contents').css('visibility', 'visible');
// And now we set up the scrolling timer
var intId = setInterval(scroll, 100);

Initially calculate the vertical beginning/ending values of all divs and store this data independently. Make all divs visible (display !== 'none')in the DOM very briefly, while using opacity to hide them, in order to calculate their heights (no way to calculate div height without attaching it to the DOM).
Also need to make all scrollable items position: absolute so that their removal doesn't reflow the items beneath them. This means javascript also needs to calculate top positions for items.
Then, whenever things change (whenever new items potentially need to be shown/hidden) check all independently stored position data against the position of the "hot zone" (the zone with which contact causes visibility).
window.onload = () => {
let positions = []; // Independently store positional data for text items
// Keep references to some useful DOM elements
let hotZone = document.getElementsByClassName('hot-zone')[0];
let scroller = document.getElementsByClassName('scroller')[0];
let scrollerHeight = scroller.getElementsByClassName('height')[0];
let items = document.getElementsByClassName('item');
let totalHeight = 0; // We'll track total height of items as we go
for (let i = 0; i < items.length; i++) {
let { height } = items[i].getBoundingClientRect();
items[i].style.top = `${Math.round(totalHeight)}px`;
items[i].style.display = 'none';
positions.push([ totalHeight, height ]);
totalHeight += height;
}
// Make sure the scroller doesn't shrink when we remove its children
scrollerHeight.style.height = `${Math.round(totalHeight)}px`;
let reevaluate = () => {
let hotRect = hotZone.getBoundingClientRect();
let scrollRect = scroller.getBoundingClientRect();
for (let i = 0; i < items.length; i++) {
let [ itemTop, itemHeight ] = positions[i];
itemTop += scrollRect.top; // Make relative to scroller
itemTop -= scroller.scrollTop; // Make relative to scroll amt
let tooHigh = itemTop + itemHeight < hotRect.top;
let tooLow = itemTop > hotRect.bottom;
let disp = (tooHigh || tooLow) ? 'none' : 'block';
if (disp !== items[i].style.display) items[i].style.display = disp;
}
};
// Immediately call `reevaluate` to initially show items
reevaluate();
// Now everything is nice so make the scroller completely opaque
document.getElementsByClassName('scroller')[0].style.opacity = '1';
// Setup listeners to call `reevaluate` when there's a possibility
// new items need to show. E.g., the "hot zone" has moved, the items
// have moved, scrolls have happened, etc.
scroller.addEventListener('scroll', reevaluate);

So you said in your comment that
but my requirement is whichever content touches that gray band should
be shown otherwise it has to be hidden holding no width and height
From this I understand that you need a vertical text scroller. Why don't you use the gray band div as a container, with overflow hidden, and then scroll the content through it?
$(function() {
var pos = 1;
var ii = 0;
var centerbandTop = $('.center-band').offset().top;
var centerbandBottom = $('.center-band').outerHeight() + centerbandTop;
//$('.contents').hide();
var intId = setInterval(function() {
ii++;
pos = -ii;
//console.log(pos);
//if (pos )
$('.contents').each(function() {
var $content = $(this);
var contentTop = $content.offset().top;
var contentBottom = $content.outerHeight() + contentTop;
//$content.hide();
//console.log($content.position().top, centerbandTop, contentBottom);
//if (centerbandBottom > contentTop && centerbandTop < contentBottom)
//$content.show();
});
$('.container').css({
// '-webkit-transform' : 'translate(0,' + pos + ')',
transform: 'translateY(' + pos + 'px)'
});
}, 100);

the band is this element <div class="center-band"></div>
whenever the scrolling element touches the element <div class="center-band"></div> then it has to be shown, and other divs have to be hidden
Question: only touched div to the band has to be shown, and others has to be hidden, that means only one content has to be shown at a time.

It depends on whether you want to include the margins or not, but you can use the following to detect the positions and then apply the class over to the .content divs that are currently hovered over:
$(function() {
var pos = 1;
var ii = 0;
var centerbandTop = $('.center-band').offset().top;
var centerbandBottom = $('.center-band').outerHeight() + centerbandTop;
var intId = setInterval(function() {
ii++;
pos = -ii;
$('.contents').each(function() {
var $content = $(this);
var contentTop = $content.offset().top;
var contentBottom = $content.outerHeight() + contentTop;
$content.removeClass('over');
if (centerbandBottom > contentTop && centerbandTop < contentBottom)
$content.addClass('over');
});
$('.container').css({
// '-webkit-transform' : 'translate(0,' + pos + ')',
transform: 'translateY(' + pos + 'px)'
});
}, 100);
});

This is not exactly the direct answer to your questions, but another approach to solve this. May be this will help you somehow.
var domRect = document.getElementById('center-band').getBoundingClientRect();
var centerBandTop = domRect.top+20;
var centerBandBottom = domRect.top + 58;
$(function(){
var pos = 1;
var ii = 0;
var intId = setInterval(function(){
ii++;
pos =- ii;
$('.container').css({
transform : 'translateY('+pos+'px)'
});
$('.contents').each(function(idx,ele){
var domContent = document.getElementsByClassName('contents')[idx].getBoundingClientRect();
// console.log(idx +'---'+ domContent.top)
if(domContent.top < centerBandBottom && domContent.bottom > centerBandTop ){
//$(ele).text('');
}
else{
//$(ele).css('color','#fff');
}
})
},100);
});

You are seeing the effects of collapsing margins between your p elements and the adjacent h3 headers.
You can prevent this by simply adding the following CSS rule:
.collapse div {
overflow: auto;
}
See demo: https://jsfiddle.net/vauxjg7r/
Fiddle demo here.
Try to add this CSS style:
.collapse p {
margin: 0px;
}
But if you want to keep the space above, you can do:
.collapse p {
margin: 0px;
padding: 10px 0 0;
}
The issue was caused by browser-applied styles, you need to overwrite them with codes like above. Or, you could use CSS resets to normalize browser styles.
It's the margin from the paragraphs. You must overwrite the user agent stylesheet by adding this to your stylesheet:
p {
margin: 0;
padding: .5em 0;
}
This is due to margin collapsing on the p elements.
If there is no border, padding, inline content, or clearance to
separate the margin-top of a block with the margin-top of its first
child block, or no border, padding, inline content, height,
min-height, or max-height to separate the margin-bottom of a block
with the margin-bottom of its last child, then those margins collapse.
The collapsed margin ends up outside the parent.
(https://developer.mozilla.org/en-US/docs/Web/CSS/margin_collapsing)
To stop this effect from happening add overflow: hidden; to .collapse > h3 + div.
