Wordpress Divi - problem with inserting code for Animated Cursor - javascript

This is my new clear site: www.talas.me
And this is what i want to copy: Awesome Link Hover Effect / Animated Cursor
(function () {
const link = document.querySelectorAll('nav > .hover-this');
const cursor = document.querySelector('.cursor');
const animateit = function (e) {
const span = this.querySelector('span');
const { offsetX: x, offsetY: y } = e,
{ offsetWidth: width, offsetHeight: height } = this,
move = 25,
xMove = x / width * (move * 2) - move,
yMove = y / height * (move * 2) - move;
span.style.transform = `translate(${xMove}px, ${yMove}px)`;
if (e.type === 'mouseleave') span.style.transform = '';
};
const editCursor = e => {
const { clientX: x, clientY: y } = e;
cursor.style.left = x + 'px';
cursor.style.top = y + 'px';
};
link.forEach(b => b.addEventListener('mousemove', animateit));
link.forEach(b => b.addEventListener('mouseleave', animateit));
window.addEventListener('mousemove', editCursor);
})();
html, body {
margin: 0;
padding: 0;
cursor: none;

There is problem somewhere and i can't figure out where. As you can see now (when i copy this code correctly) we can't see the cursor on my site.
Can someone tell me what is the problem and how to fix it?
This is very important for my site because the site will be black and white, and this cursor effect is so important to me.
Thank you!

as far as i know that Divi theme provide a option in theme settings where we can add custom jQuery or javascript so you can directly add over there
this below link may help you to resolve issue

Newbie to stackoverflow here, so please let me know if there are any issues with this question.
I'm encountering an issue where expanding the accordion on my website causes the parallax background image to jump downwards, because the website content height changes. However, what puzzles me is that this issue only happens on iOS (both Safari and Chrome apps). The parallax seems to be fine on Android and both Safari and Chrome on Mac.
I've implemented "performative parallax" that is described here.
GIF of issue
The actual website is accessible here. Code hosted on Github.
I'm not very experienced in HTML/CSS and/or JS, but I've fiddled around with the parallax JS/CSS to no avail.
I've also seen similar issues discussed here and here, but neither solution fixed the issue (or I may have done something incorrectly).
Thank you so much for your help!
EDIT (also in comment): Came up with a temporary solution – literally just added the code below to the JS. I know it's a hacky workaround, but works surprisingly well.
// create an Observer instance
const resizeObserver = new ResizeObserver(entries => {
// console.log('Body height changed:', entries[0].target.clientHeight);
onResize(parallaxDetails);
});
// start observing a DOM node
resizeObserver.observe(document.getElementsByClassName("parallax-container")[0]);

Hiding/Showing CSS elements does not work?

HTML:
<section id="section">
<div class="content">
<button id="btn"></button>
<button id="btn1"></button>
</div>
</section>
to then execute the next function function next(). This removal is needed because when I don't remove the elements from the first function the second wont work. I could just do document.head.innerHTML = "" but that would then also remove the css needed for the button appearing in the next function. So then I tried to make variables with const
const btn = document.getElementById('text');
const btn1 = document.getElementById('text1');
const section = document.querySelector('section')
// in function Seifenblasen_blasen()
btn1.style.display = 'none';
// in function next()
section.style.display = 'none';
btn.style.display = 'none';
btn1.style.display = 'block';
to hide and show only parts of the css without removing the css entirely to keep the styling intact, but now nothing works anymore.(the button on the next Screen doesn't show up at all and the first button does not contain any styling) My endgoal is that I can essentially switch between two screens one showing the bubbles and one the bouncy balls and when I click on the button it goes on. (for example start is bubbles. I click -> Bounce, click again -> back to Bubbles and so on)

Why the z-index value does upset the functioning of my animation?

I'm trying recoding the https://www.orizon.co/ following dot. The code I've written to asure the dot rising effect when the pointer fly over some elements seems correct, but when the dot's z-index is higher than the flew over element's one, there is a kind of bug than make me crazy.
class CursorFollower {
constructor() {
this.follower = document.getElementById("cursor-follower");
this.topGap = 12;
this.leftGap = 4;
window.addEventListener("mousemove", this.follow.bind(this));
this.eventsSet();
}
// The function doing the dot follows the pointer
follow() {
setTimeout(function () {
cursorFollower.follower.style.left = (this.clientX - cursorFollower.topGap) + "px";
cursorFollower.follower.style.top = (this.clientY - cursorFollower.leftGap) + "px";
}.bind(window.event), 100);
}
eventsSet() {
// Adding events to button
var button = document.querySelector(".follower-over");
button.addEventListener("pointerenter", this.overOn.bind(this));
button.addEventListener("pointerleave", this.overOff.bind(this));
}
overOn() {
// The effects to apply when the pointer flies over the button
this.follower.style.opacity = 0.3;
this.follower.style.width = "50px";
this.follower.style.height = "50px";
this.follower.style.backgroundColor = "black";
this.topGap = 25;
this.leftGap = 25;
}
overOff() {
// The effects to apply when the pointer leave the button
this.follower.style.opacity = 1;
this.follower.style.width = "7px";
this.follower.style.height = "7px";
this.follower.style.backgroundColor = "rgba(42, 0, 212, 1)";
this.topGap = 12;
this.leftGap = 4;
}
}
let cursorFollower = new CursorFollower();
/* Some styling */

When the button's z-index is higher than the dot's one, the effects works. Else, it bugs
This is because your follower element is getting under cursor, triggering overOff than when its shrinks it triggers overOn and so on.
The simplest solution is to add pointer-events: none; into the follower so it doesn't trigger overOn/overOff:
class CursorFollower {
constructor() {
this.follower = document.getElementById("cursor-follower");
this.topGap = 12;
this.leftGap = 4;
window.addEventListener("mousemove", this.follow.bind(this));
this.eventsSet();
}
// The function doing the dot follows the pointer
follow() {
setTimeout(function() {
cursorFollower.follower.style.left = (this.clientX - cursorFollower.topGap) + "px";
cursorFollower.follower.style.top = (this.clientY - cursorFollower.leftGap) + "px";
}.bind(window.event), 100);
}
eventsSet() {
// Adding events to button
var button = document.querySelector(".follower-over");
button.addEventListener("pointerenter", this.overOn.bind(this));
button.addEventListener("pointerleave", this.overOff.bind(this));
}
overOn() {
// The effects to apply when the pointer flies over the button
this.follower.style.opacity = 0.3;
this.follower.style.width = "50px";
this.follower.style.height = "50px";
this.follower.style.backgroundColor = "black";
this.topGap = 25;
this.leftGap = 25;
}
overOff() {
// The effects to apply when the pointer leave the button
this.follower.style.opacity = 1;
this.follower.style.width = "7px";
this.follower.style.height = "7px";
this.follower.style.backgroundColor = "rgba(42, 0, 212, 1)";
this.topGap = 12;
this.leftGap = 4;
}
}
let cursorFollower = new CursorFollower();
/* Some styling */
.contact-us {
padding: 25px 40px;
width: 200px;
display: flex;
align-items: center;
color: white;
background-color: #2b00d4;
height: 60px;
position: relative;
z-index: 1;
}
#cursor-follower {
pointer-events: none; /* added */
z-index: 999;
position: fixed;
background-color: #2b00d4;
height: 7px;

}

However there is even simpler solution with much less javascript:
window.addEventListener("mousemove", e => {
setTimeout(s => {
document.documentElement.style.setProperty("--cursorX", e.clientX + "px");
document.documentElement.style.setProperty("--cursorY", e.clientY + "px");
}, 100);
});
/* Some styling */
:root
{
--cursorX: -100px;
--cursorY: -100px;
}
.contact-us {
padding: 25px 40px;
width: 100px;
display: flex;
align-items: center;
color: white;
background-color: #2b00d4;
height: 40px;
position: relative;
z-index: 1;
}
.cursor-follower {
--size: 7px;
--gapLeft: 12px;
--gapTop: 4px;
pointer-events: none;
position: fixed;
background-color: #2b00d4;
width: var(--size);
height: var(--size);
border-radius: 50%;
transition: opacity 0.3s, width 0.3s, height 0.3s, background-color 0.3s;
top: calc(var(--cursorY) - var(--gapTop));
left: calc(var(--cursorX) - var(--gapLeft));
}
.follower-over:hover~.cursor-follower {
--size: 50px;
--gapLeft: 25px;
--gapTop: 25px;
opacity: 0.3;
background-color: black;
z-index: 2;
}
/* extra */
.follower-over.green:hover~.cursor-follower {
background-color: green;
opacity: 0.7;
--size: 80px;
--gapLeft: 40px;
--gapTop: 40px;
}
.contact-us:not(.follower-over) {
background-color: pink;
}
.contact-us {
display: inline-block;
margin: 1em;
}
<div class="contact-us follower-over">
<p>CONTACT US</p>
</div>
<div class="contact-us follower-over">
<p>Another button</p>
</div>
<div class="contact-us">
<p>No follower</p>
</div>
<div class="contact-us follower-over green">
<p>Large green</p>
</div>
<div class="cursor-follower"></div>
The only caveat with this method is the .cursor-follower must be last element and has the same parent as all .follower-over elements

Why is there a random space when you click on this button?

I have been trying to replicate some material design buttons but have run into an issue with the div that is generated to create the "ripple" effect. If you go to my codepen at https://codepen.io/AlexStiles/pen/oPomzX you will see the issue.
This is caused by the div (I tried deleting it and it fixed the problem). I have tried adding a variety of properties such as font-size and line-height to no avail. Interestingly, depending on your browser the issue seems to have a different effect. On safari the width increases hugely then it decreases to the chrome width.
"use strict";
const buttons = document.getElementsByTagName("button");
const overlay = document.getElementsByClassName("overlay");
const animationTime = 600;
for (let i = 0; i < buttons.length; i++) {
buttons[i].addEventListener("click", createRipple);
};
let circle = document.createElement("div");
function createRipple(e) {
this.appendChild(circle);
var d = Math.max(this.scrollWidth, this.scrollHeight);
circle.style.width = circle.style.height = d + "px";
circle.style.left = e.clientX - this.offsetLeft - d / 2 + "px";
circle.style.top = e.clientY - this.offsetTop - d / 2 + "px";
circle.classList.add("ripple");
// setTimeout(function(){
// for (let i = 0; i < circle.length; i++)
// document.getElementsByClassName("ripple")[i].remove();
// }, animationTime);
}

Change
button *:not(:last-child) {
margin: 0 8px 0 0;
}
To,
button *:not(:last-child) {
margin: 0 0 0 0;
}
Checked in firefox.
When you add the ripple element you make it the last-child thus the rule of margin button *:not(:last-child) will apply to span since this one is no more the last child.
To fix this remove margin from the span:
"use strict";
const buttons = document.getElementsByTagName("button");
const overlay = document.getElementsByClassName("overlay");
const animationTime = 600;
for (let i = 0; i < buttons.length; i++) {

Why is my responsive navigation bar, made with Javascript, working only after refresh in iPhone browsers?

If a user, using iPhone (actual devices), lands on my website for the first time the "hamburger menu" will not open the menu at all, and navbar will not appear on scrolldown. It seems to be working just fine on Android devices (except maybe Nexus 4 in portrait mode if we were to believe responsinator ), and Win desktops.
The actual website's backend is made with Razor/ASP.NET but obviously I believe this is a pure frontend issue.
After a refresh it starts to work on Apple devices (well, iPhone) as well. And then sometimes stops working (once or twice it stopped working again, I believe).
Head (tried removing async and defer, did not work):
<script type="text/javascript" src="script.js" async defer></script>
Here is HTML (with bad usage of h2 tag with logo image in it):
<div id="navigation-main">
<h2 class="logo">
<a href="#">
<img src="images/white-logo.png" alt="">
</a>

Javascript:
(function() {
////////// Sticky navbar and hamburger icon
var headerScroll = getId('navigation-main'),
scrollHeight = 250,
menuIcon = getId('menu-icon'),
menuMain = getId('menu-main'),
classMenu = 'menu-active',
classHeader = 'active';
// Scroll
window.addEventListener("scroll", scrollOn);
function scrollOn() {
animatedScroll(headerScroll, classHeader, scrollHeight);
}
// Responsive menu
menuIcon.onclick = function() {
toggle(menuMain, classMenu);
}
menuMain.onclick = function() {
toggle(menuMain, classMenu);
}
// Moving the element after scrolling
function animatedScroll(element, classN, height) {
y = pageYOffset;
if (y > height) {
element.className = classN;
} else {
element.className = '';
}
}
// Change the element's class
function toggle(element, classe) {
element.className = element.className ? '' : classe;
}
// Return the element
function getId(id) {
return document.getElementById(id);
}
////////// Sticky navbar and hamburger icon
// Feature Test
if ('querySelector' in document && 'addEventListener' in window && Array.prototype.forEach) {
// Function to animate the scroll
var smoothScroll = function(anchor, duration) {
// Calculate how far and how fast to scroll
var startLocation = window.pageYOffset;
var endLocation = anchor.offsetTop;
var distance = endLocation - startLocation;
var increments = distance / (duration / 16);
var stopAnimation;
// Scroll the page by an increment, and check if it's time to stop
var animateScroll = function() {
window.scrollBy(0, increments);
stopAnimation();
};
// If scrolling down
if (increments >= 0) {
// Stop animation when you reach the anchor OR the bottom of the page
stopAnimation = function() {
var travelled = window.pageYOffset;
if ((travelled >= (endLocation - increments)) || ((window.innerHeight + travelled) >= document.body.offsetHeight)) {
clearInterval(runAnimation);
}
};
}
// If scrolling up
else {
// Stop animation when you reach the anchor OR the top of the page
stopAnimation = function() {
var travelled = window.pageYOffset;
if (travelled <= (endLocation || 0)) {
clearInterval(runAnimation);
}
};
}
// Loop the animation function
var runAnimation = setInterval(animateScroll, 16);
};
// Define smooth scroll links
var scrollToggle = document.querySelectorAll('.scroll');
// For each smooth scroll link
[].forEach.call(scrollToggle, function(toggle) {
// When the smooth scroll link is clicked
toggle.addEventListener('click', function(e) {
// Prevent the default link behavior
e.preventDefault();
// Get anchor link and calculate distance from the top
var dataID = toggle.getAttribute('href');
var dataTarget = document.querySelector(dataID);
var dataSpeed = toggle.getAttribute('data-speed');
// If the anchor exists
if (dataTarget) {
// Scroll to the anchor
smoothScroll(dataTarget, dataSpeed || 500);
}
}, false);
});
}
})();
And here is JSFiddle.
If it's touchstart/onclick issue why does it work after the refresh? Should I remove IFFE? Should I put script tag at the end of the page?
What seems to be the issue here?
Apparently the line in the header was an issue.I have removed "async" and the navigation menu started working.
<script type="text/javascript" src="script.js" async defer></script>
changed to:
<script type="text/javascript" src="script.js" defer></script>
