a href's not working from inside a modal popup NOT BOOTSTRAP, NOT JQUERY

The aside element is a modal popup with multiple a href links inside, none of which are working. I can right click and go to the link but clicking on it does nothing. The open modal is triggered by Javascript. There are no external libraries, plugins etc that could be causing conflict.
What am I missing here?
const overlay = document.querySelector(".overlay");
const card = document.querySelectorAll(".card");
card.forEach((card) => {
card.addEventListener("click", () => {
const cardId = card.getAttribute("data-card");
const modal = document.getElementById(`${cardId}`);
modal.classList.remove("hidden");
overlay.classList.remove("hidden");
const vScrollPos = window.scrollY;
document.body.style.position = "fixed";
document.body.style.top = `-${vScrollPos}px`;
const closeModal = function() {
modal.classList.add("hidden");
overlay.classList.add("hidden");
const scrollY = document.body.style.top;
document.body.style.position = "";
document.body.style.top = "";
window.scrollTo(0, parseInt(scrollY || "0") * -1);
};
const modalCloseBtn = modal.querySelector(".close-modal");
modalCloseBtn.addEventListener("click", () => {
closeModal();
});
overlay.addEventListener("click", closeModal);

Ok. issue has been found and fixed.
I was using scrollIntoView to handle page nav and smooth scrolling and I imprecisely targeted all "a" elements before I wrote the code for this current section with "a" elements inside of modal containers. Solved issue by giving the page nav a's an additional class then targeting that class only for that section of JS code! Doooooh.

Custom cursor is reset to top left of page every time a new page is loaded

I have a custom cursor on my site that is working perfectly apart from one thing. When clicking through to a new page, when the page loads the cursor resets itself to the top left of the page regardless of where you leave the mouse on the page, then once you moved the mouse the cursor moves back to where the mouse is. I have tried removing "top" & "left" from the CSS but the problem remains. I cant see what is causing this to happen, and I just need the cursor to stay where the mouse is positioned on the page and not reset every time you navigate to a new page.
jQuery(document).ready(function($) {
let cursor = document.querySelector('#custom-cursor');
if(/Android|webOS|iPhone|iPad|iPod|BlackBerry|Windows Phone/i.test(navigator.userAgent)) {
$('#custom-cursor').remove();
}
else { cursor.style.display = 'block';}
document.addEventListener('mousemove', evt => {
let { clientX: x, clientY: y } = evt;
let scale = 1;
if (evt.target.matches('a,span,[onclick],img,video,i')) {
cursor.classList.add('active');
scale = 0.5;
} else {
cursor.classList.remove('active');
}
cursor.style.transform = `translate(${x}px, ${y}px) scale(${scale})`;
});
});

Use ordinary CSS cursor as shown in the other answer and replace it with you fancy cursor in the first mouse event:
jQuery(document).ready(function($) {
let cursor = document.querySelector('#custom-cursor');
document.addEventListener('mousemove', evt => {
document.body.classList.add('custom-cursor-moved')
if (/Android|webOS|iPhone|iPad|iPod|BlackBerry|Windows Phone/i.test(navigator.userAgent)) {
$('#custom-cursor').remove();
} else {
cursor.style.display = 'block';
}
let {
clientX: x,
clientY: y
} = evt;
let scale = 1;
if (evt.target.matches('a,span,[onclick],img,video,i')) {
cursor.classList.add('active');
scale = 0.5;
} else {
cursor.classList.remove('active');
}
cursor.style.transform = `translate(${x}px, ${y}px) scale(${scale})`;
});
});

Try me.<br> Try me.
It needs a bit of modifications (better cursor image, fix it hotspot etc.) but it works.
Be very, very careful when doing such thing. Try to not break any accessibility tools and please do not assume that Android/some specific user-agent HAS touchscreen, etc.. Use proper APIs.

Use CSS cursor property instead:
html {
cursor: url(https://cdn.sstatic.net/Sites/stackoverflow/Img/favicon.ico?v=ec617d715196) 0 0, auto;
height: 100%;
}

Carousel prev and next button logic does not work

I am trying to a make carousel using pure Javascript. I successfully manage to slide the carousel and have created left and right buttons.
I took my slide functions and added them to the button on-click event-listener, but I have problems when I implement the function on my buttons. It does not behave as expected. My code is below, how can I fix this?
const images = document.getElementById('imgs'); //here
const allImages = document.querySelectorAll('#imgs img');
const leftBtn = document.getElementById('left');
const rightBtn = document.getElementById('right');
let index = 0;
function changeSliderPage() {
const dot = [...document.getElementsByClassName('star')];
index++;
if (index > allImages.length - 1) {
index = 0
}
imgs.style.transform = `translateX(${-index * 500}px)`;
dot.forEach((dot, i) => {
if (i === index) {
dot.classList.add('active')
} else {
dot.classList.remove('active')
}
});
};
allImages.forEach(i => {
const elem = document.createElement('div');
elem.classList.add('star');
document.body.appendChild(elem)
});
rightBtn.onclick = () => {
changeSliderPage(index + 1);
}
leftBtn.onclick = () => {
changeSliderPage(index - 1);
}
let x = setInterval(changeSliderPage, 100000);
images.onmouseover = () => {
clearInterval(x)
}
images.onmouseout = () => {
x = setInterval(changeSliderPage, 2000);
}

Logic that I use with carousels:
for example you have 4 images:
[1][2][3][4]
I have an animation for sliding every image, I add 5th image which is same as image no 1:
[1][2][3][4][1]
Imagine cursor which shows what image is currently displayed, Ill mark cursor as ! !
So at begin:
[!1!][2][3][4][1]
Now the slider moves on...
[1][!2!][3][4][1]
etc...
It moves to last image:
[1][2][3][4][!1!]
And now it has to move under the hood from last image to first image, but without any animation so the whole change is not visible by user:
[!1!][2][3][4][5]
This way you can get inifinite carousel, just need to check in javascript if current image is last one and you want to slide right -> no animation. Same if you are on 1st image and want to slide left.

How to add class on specific div when scroll?

I am playing around and practice my JS (beginner). I have created stacking panels and i hit a wall. I just can not target and add class of shadow to the moving element (only when one panel is above other, class should add).
For now i have this:
const boxes = Array.from(document.querySelectorAll(".box"));
const wrapper = document.querySelector(".wrapper");
const leftMargin = 60; //px
function scrollWrap(e) {
let scrollCoord = wrapper.scrollLeft; // horizontal scroll value
boxes.forEach((box, index) => {
let leftMarginStop = index * leftMargin;
const boxCoord = box.getBoundingClientRect();
let leftCoordPanel = boxCoord.left;
let flag = false;
//console.log({scrollCoord, leftMarginStop, leftCoordPanel, box});
if (boxCoord.left <= leftMarginStop) { // if left side of pannel is less than margin 60, 120, 180,...
//console.log("STAHP!!");
box.style.position = "sticky";
box.style.left = `${leftMarginStop}px`; // sets the left to 60, 120, 180,...
flag = true;
if (flag) {
box.classList.add("shadow");
console.log(this) //how to target each panel rather than wrapper?
} else {
box.classList.remove("shadow");
}
} else {
box.style.position = "static";
box.style.left = 0;
flag = false;
}
});
}
wrapper.addEventListener("scroll", scrollWrap);
body {
margin: 0;
padding: 0;
}

If anyone can help me out, please show me code with explanation, so i can see and know what and how.
I try to do it with some flag or without, but every time the class is added when element reaches the end (left padding). I want to add class when element is on top of other element. If it is not, remove class. Also, how to make this so it works on mouse scroll wheel? I was testing this with apple magic mouse, but on scroll wheel it does not work.
Oh and please, if you see something very wrong please let me know, i am beginner and would like to learn something from this post.

For now i have managed to update my code. It works when i scroll and shadow is also applying to the panel. There is still something i wonder.
When i add shadow class i created transition. It works perfect, but when i remove shadow class it just disappears, no transition back. Why is that? I want shadow to appear and disappear in same way
How to track every single panel if it has reached the left margin, and than apply eventListener with mouse enter and mouse leave on it? So when i hover to "closed" panel, i get that item and if i hover on NOT "closed" panel i will not get item. I was trying with console.log "this" but it returned every panel i mouse entered it
How to target every panel, so i can later say, when 4th panel reaches left margin, the margin of stacked elements change?
My updated code:
const boxes = Array.from(document.querySelectorAll(".box"));
const wrapper = document.querySelector(".wrapper");
const leftMargin = 60; //px
function scrollWrap(e) {
let scrollCoord = wrapper.scrollLeft; // horizontal scroll value
boxes.forEach((box, index) => {
let leftMarginStop = (index) * leftMargin; // calculation for left margin stop (60, 120, 180,...)
const boxCoord = box.getBoundingClientRect();
const leftSideOfCurrent = boxCoord.left; // coordinarion of left side of panel
const rightSideOfCurrent = boxCoord.right; // coordinarion of right side of panel
const leftSideOfNextItem = box.nextElementSibling.getBoundingClientRect().left; // coordinarion of left side of NEXT panel
box.style.position = "sticky";
box.style.left = `${leftMarginStop}px`;
// controll shadow of first element
scrollCoord > 0 ? boxes[1].classList.add("shadow") : boxes[1].classList.remove("shadow");
// controll shadow of all 0+ elements
if (leftSideOfCurrent <= leftMarginStop) { // if left side of pannel is less than margin 60, 120, 180,...
box.nextElementSibling.classList.add("shadow");
}
// controll removal of shadow of all 0+ elements
if (leftSideOfNextItem === rightSideOfCurrent) {
box.nextElementSibling.classList.remove("shadow");
}
// when panel 5 reach left margin, left margin change from 60 to 30 to all panels
if (boxes[4] && leftSideOfCurrent < leftMarginStop) {
console.log("helo");

Tips for your code:
In your CSS code, the wrapper element has a width property. This
causes the page and the wrapper element to have a scrollbars. So,
remove it.
You do not need to use javascript to add stickiness to the
boxes. The only CSS will do this for you. You need JavaScript only
for add the left property and shadow to the boxes.
Don’t try to use overflow: auto|scroll|hidden on the parent element
of a position:sticky element. It completely breaks the stickiness.
overflow: visible is fine. See the code snippet below.
In your JavaScript code, the flag variant value, always is true, So
the shadow class can't remove from elements.
Other notes:
If you’re wanting to use position:absolute on an element inside of
a sticky element you have to be careful. If your app is running in
an older browser that doesn’t support position:sticky, then that
sticky element won’t act like a relative positioned element. So
the absolute positioned element will skip it and look up the DOM
tree until it finds the next non-static element (absolute / relative / fixed position), defaulting to the html element if none
found. In other words, your absolute positioned element is going
to be in a way different place on the screen than you expected it to
be.
position: sticky; is supported in a lot of browsers, but not yet
in Edge. IE doesn’t matter at this point. There are many
polyfills out there if you absolutely have to have this behavior,
but they all use JavaScript. A better option is to design your app
so that sticky position is a slick addition, but the app still
functions without it.
Example:
const boxes = Array.from( document.querySelectorAll( '.box' ) ),
scroller = document.querySelector( '.scroller' ),
leftMargin = 30,
length = boxes.length - 1;
function scrollWrap() {
boxes.forEach( function( box, index ) {
let leftMarginStop = index * leftMargin;
const boxCoord = box.getBoundingClientRect();
let leftCoordPanel = boxCoord.left;
if ( leftCoordPanel <= leftMarginStop ) {
box.style.left = leftMarginStop + 'px';
if ( index < length ) boxes[ index + 1 ].classList.add( 'shadow' )
if ( index == 0 && boxes[ 1 ].getBoundingClientRect().left == box.offsetWidth ) boxes[ 1 ].classList.remove( 'shadow' )
} else {
box.style.left = 0;
if ( index < length ) boxes[ index + 1 ].classList.remove( 'shadow' )
}
} );

About your updated code:
the following line in your jS code:
const leftSideOfNextItem = box.nextElementSibling.getBoundingClientRect().left;
causes an error. Because, when index become 8, box.nextElementSibling can't retrieve any element. So you can change it to this:
const leftSideOfNextItem = ( index < boxes.length - 1 ) ? box.nextElementSibling.getBoundingClientRect().left : 0;
Also at the end of your JS code, the following code snippet:
if (index[4] && leftSideOfCurrent < leftMarginStop) {
console.log("helo");
}
must change to:
// when panel 5 reach left margin, left margin change from 60 to 30 to all panels
if (index == 4 && leftSideOfCurrent <= leftMarginStop) {
console.log("helo");
leftMargin = 30
}
Also you must change const leftMargin = 60; to var leftMargin = 60;
Updated code:
const boxes = Array.from(document.querySelectorAll(".box"));
const wrapper = document.querySelector(".wrapper");
var leftMargin = 60; //px
function scrollWrap(e) {
let scrollCoord = wrapper.scrollLeft; // horizontal scroll value
boxes.forEach((box, index) => {
let leftMarginStop = (index) * leftMargin; // calculation for left margin stop (60, 120, 180,...)
const boxCoord = box.getBoundingClientRect();
const leftSideOfCurrent = boxCoord.left; // coordinarion of left side of panel
const rightSideOfCurrent = boxCoord.right; // coordinarion of right side of panel
const leftSideOfNextItem = ( index < boxes.length - 1 ) ? box.nextElementSibling.getBoundingClientRect().left: 0; // coordinarion of left side of NEXT panel
box.style.position = "sticky";
box.style.left = `${leftMarginStop}px`;
// controll shadow of first element
scrollCoord > 0 ? boxes[1].classList.add("shadow") : boxes[1].classList.remove("shadow");
// controll shadow of all 0+ elements
if (leftSideOfCurrent <= leftMarginStop) { // if left side of pannel is less than margin 60, 120, 180,...
box.nextElementSibling.classList.add("shadow");
}
// controll removal of shadow of all 0+ elements
if (leftSideOfNextItem === rightSideOfCurrent) {
box.nextElementSibling.classList.remove("shadow");
}
// when panel 5 reach left margin, left margin change from 60 to 30 to all panels
if (index == 4 && leftSideOfCurrent <= leftMarginStop) {
console.log("helo");
leftMargin = 30
}
});
}

This was helpful. I know for error but could not fix it. I have set let leftMargin = 60; i use let instead var.
I am working on the margins, if the 5th panel reaches the left margin the margin of all panels get 30px. I did it also for reverse:
if (index > 4 && leftSideOfCurrent <= leftMarginStop) {
leftMargin = 30;
} else if (index < 5 && leftSideOfCurrent > leftMarginStop) {
leftMargin = 60;
}
But now when 5th panel reaches left margin, the panels less than 5 get EACH transitioned seperately instead of all, but when the 5th element is no longer in left margin, all gets transitioned at same time. Why is it like that? I do not understand. Can you explain please?

You have mentioned the height of the image to be 100% while defining ".carousel-content img" class.Try as below :
.carousel-content img {
position: fixed;
top: 0;
bottom: 0;
left: -90%;
right: 0;
overflow: auto;
}
Edit
The general thing to be kept in mind while working with the image :
we must not change the proportion of the image to prevent it from being distorted. hence, we can work either on width or on height, keeping the other one set to "Auto".
Definitely, the image will settle itself according to what we have defined for its width and height. So if there won't be enough space to accommodate the whole image, the part of it will be cropped of ( or you say, stays hidden )
