Need help to hover different background images in wordpress HTML code

I want exactly like this website: https://www.petzl.com/INT/en
I have displayed background video, 3 texts, by hovering on them the images are changing + links to access them.
But by hovering the text, petzl.com website have activated different images on hover, sometimes different images are appearing on hover.
Can I achieve the different images by css or need to have js or anything? Also need to have span/div elements to appear in one line.
My website link: beta.edgerope.com
Please find code below:
Below is the code, I have added as HTML shortcode in the page and in the background video is displayed
<style>
.image{

There are many ways to acomplish this, and you should be able to do this with pure css and html.
I've made an example that uses css pseudo elements in order to display the correct image when hovering the sections/links. Also changed up to use a tags instead of using onclick="window.location" as you did.
Here you can change/set the default image in the #hero selector
<style>
/* Styling for the default hero */
#hero {
height: 800px;
width: 100%;
display: flex;
color: black;
background-color: #000;
}
/* Wrapper for all the sections */
.hero-sections {
width: 100%;
height: 100%;
position: relative; /* Allows to change the z-index, and */
z-index: 1;
display: flex;
flex-direction: row;
justify-content: center;
align-items: center;
gap: 2rem;
}
/* Container for the image */
.hero-image::after {
content: "";
position: absolute;
left: 0;
top: 0;
width: 100%;
height: 100%;
z-index: -1; /* Allows the image to appear behind the text */
pointer-events: none; /* Prevent image to show when hovering the ::after element*/
background-image: var(
--bg-url
); /* Uses the images set by the html (css variable) */
opacity: 0; /* Hides the image when it's not active */
transition: opacity 0.5s; /* Adds a fade transition to the opacity*/
}
/* Styles when the the user hovers or has focus on the buttons/links */
.hero-image:is(:hover, :focus-within)::after {
opacity: 1; /* Change the opacity when the text is active/in hover */
}
/* Styles the buttons/links */
.hero-cta {
color: white;
text-decoration: none;
font-size: 2rem;
}
</style>
<div id="hero">
<div class="hero-sections">
<div
class="services hero-image"

If you would like to go more advanced here I would recommend implementing some javascript handling mouseenter and mouseleave. As you said you used Wordpress you could also use the .hover() from jQuery.

HTML/CSS/JS - Overlay backgrounds for modal popups - Issues with

I'm trying to add a semi-opaque overlay to my page that supports multiple modal popups.
The three popup boxes open OK without the need for Javascript, and, with the help of some Javascript, they close by mouse-clicking outside the popups.
Unfortunately, I can't get my overlay to work, without blocking the 'open-modal' buttons. I've tried wrapping the entire 'overlay' div around all the popup boxes, and I've tried keeping the popups outside of the overlay div.
Is there a way to fix this without blocking access to the buttons, and without messing up the 'external close' feature as facilitated by the Javascript?
Three files are attached: ‘.index.html’, ‘style.css’, and ‘modal-script.js’.
Apologies if my terminology is sometimes ‘homespun’, but I’m just and enthusiast doing the best I can.
My code so far is below in this same document. I would be grateful for any suggestions.

Add z-index:11 to .modal-content class and remove display:none from .modal class or add display:block to .modal class when clicking button.
If you want to access 3 buttons also when modal popup is appear add z-index: 11; position: relative; in .type_1-button class.

Add z-index:-1; to .modal and change some javascript as below
// JAVASCRIPT FILE: js/modal-script.js
// Closes multi-modals in an HTML page
// SET VARIABLES:
var boxArray = ['box1','box2','box3'];

Thanks for your feedback, people. I wasn't happy with my own solution, so I took it back to the 'drawing board' with all of your valuable comments in mind.
My code now produces a set of three interchangeable modals with two options for closing - press the 'X' symbol or mouse click the background. I will be looking for the third option of closing by [Esc.] key later. Pleas let me know if you have any recommended methods for closing with the escape key.
The overlay window opens and closes at the right moments without interfering with other elements. I hope this make a worthwhile exemplar for anyone looking for modal solutions.
The code is about to follow.
Thank you all,
Adrian McG

How make a modal transition?

I'm trying to animate a modal with a transition. I'm just looking for open it slowly but i don't understand how it works...
The modal have to be open from the center of the screen or from the screen down side.
I found this code from google :
https://codepen.io/designcouch/pen/obvKxm
But it's really too complicated for me. I can't understand how adapt it with my code...
/*Ouvrir le popup stress */
// Get the modal
var hydricstressmodal = document.getElementById('hydricstressmodal');
// Get the button that opens the modal
var stress = document.getElementById("stress");
// Get the <span> element that closes the modal
var hydricstressspan = document.getElementsByClassName("stressclose")[0];
// When the user clicks the button, open the modal
stress.onclick = function() {
hydricstressmodal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
hydricstressspan.onclick = function() {
hydricstressmodal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == hydricstressmodal) {
hydricstressmodal.style.display = "none";
}
}
/*Ouvrir le popup vegetal */
// Get the modal
var vegetalmodal = document.getElementById('vegetalmodal');
// Get the button that opens the modal
var vegetal = document.getElementById("vegetal");
// Get the <span> element that closes the modal
var vegetalspan = document.getElementsByClassName("vegetalclose")[0];
// When the user clicks the button, open the modal
vegetal.onclick = function() {
vegetalmodal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
vegetalspan.onclick = function() {
vegetalmodal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == vegetalmodal) {
vegetalmodal.style.display = "none";
}
}

A simple solution with css animations:
$('#open').click(function() {
$('#modalOverlay').show().addClass('modal-open');
});
$('#close').click(function() {
var elem = $('#modalOverlay');
elem.removeClass('modal-open');
setTimeout(function() {
elem.hide();
},200);
});
#modalOverlay {
position: fixed;
top:0;
left:0;
right:0;
bottom:0;
background-color: rgba(0,0,0,0.8);
z-index:9999;
}
#modal {
position:fixed;
width:60%;
top:55%;
left:50%;
padding:15px;
text-align:center;
background-color:#fafafa;
box-sizing:border-box;
opacity:0;
transform: translate(-50%,-50%);
transition:all 150ms ease-in-out;
}
#modalOverlay.modal-open #modal {
opacity:1;
top:50%;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="open" type="button">View modal</button>
<div id="modalOverlay" style="display:none;">
<div id="modal">
<h1>My modal</h1>
<p>This is a simple modal</p>
<button id="close" type="button">Close</button>
</div>
</div>

If you don't want to spend too much time on this kind of feature you could use a library like https://sweetalert2.github.io/ which is very easy to use and do the job.

You can also use library like bootstrap. For bootstrap modal you can refer below link.

Issue's with Modal images becoming background image

I'm fairly new to this all together so if there is an answer already out there, I apologize.I'm having major issues with the modal images on my page. For some reason when the modal image is launched it ends up being in the background of the site and the text and other content ends up being on top.
Here is the link to view: http://demottdrapery.com/project/expirement/
Below is my current coding for this page.
<table class="dylan">
<tr>
<div class="goku">
<td class="talks">
<img id="myImg" src="http://demottdrapery.com/wp-
content/uploads/2017/12/MASTER-BED-1-
1.jpg"style="width:100%;height:auto;"class="visual">
</td>
</div>
<div class="goku">
<td class="talks">
<img id="myImg" src="http://demottdrapery.com/wp-
content/uploads/2017/12/DINING-ROOM-1-1.jpg"style="width:100%;
height:auto;"class="visual">
</td>
</div>
<div id="myModal" class="modal">
<img class="modal-content" id="img01">
</div>
</tr>
</table>
<script>
// create references to the modal...
var modal = document.getElementById('myModal');
// to all images
var images = document.getElementsByClassName('visual');
// the image in the modal
var modalImg = document.getElementById("img01");
// Go through all of the images with our custom class
for (var i = 0; i < images.length; i++) {
var img = images[i];
// and attach our click listener for this image.
img.onclick = function (evt) {
console.log(evt);
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
</script>
<style>
#myImg {
cursor: pointer;
transition: 0.3s;
}
.modal {
display: none;
/* Hidden by default */
position: fixed ;
/* Stay in place */
z-index:100;
/* Sit on top */
padding-top: 100px;
/* Location of the box */
left: 0;
top: 0;
width: 100%;
/* Full width */
height: 100%;
/* Full height */
overflow: hidden;
/* Enable scroll if needed */
background-color: rgb(0, 0, 0);
/* Fallback color */
background-color: rgba(0, 0, 0, 0.9);
/* Black w/ opacity */
}
.modal-content {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
}
#keyframes zoom {
from {
transform: scale(0)
}
to {
transform: scale(1)
}
}
#media only screen and (max-width: 700px) {
.modal-content {
width: 100%;
}
.dylan{
margin: 50px auto 0;
width:100%;
border-spacing:20px 0;
}
.talks{
position: relative;
overflow: hidden;
overflow-x: hidden;
overflow-y: hidden;
padding-top:45%;
}
.visual{
position:absolute;
top: 0;
left:0;
background-position: center center;
background-size: cover;
background-repeat: no-repeat;
}
.goku{
position: relative;
overflow: hidden;
overflow-x: hidden;
overflow-y: hidden;
}
}

Any z-index applied to elements within that parent element will only apply to other elements within that parent. All the elements within the parent will be stacked accordingly, then that entire element will be put behind the text as specified by its stack order.
Move the modal div above the rest of the page content. You may need to rewrite your js after this I am not great at JS.
<div id="myModal" class="modal">
<img class="modal-content" id="img01">
</div>
<div data-vc-full-width="true" data-vc-full-width-init="true" data-vc-stretch-content="true" class="vc_row wpb_row vc_row-fluid vc_custom_1474396432392 vc_row-has-fill vc_row-o-equal-height vc_row-o-content-middle vc_row-flex" style="position: relative; left: -15px; box-sizing: border-box; width: 1116px;">

Auto focus on Modal View

What I want to accomplish is auto focus on the modal view. To explain it a bit further. I want it so that when I click on my image on my web page and it opens up the modal view it should automatically focus on the modal allowing me to scroll up and down without me having to click on the image to bring it on focus to be able to scroll up and down using my keyboard.

JavaScript
// Get the modal
var modal = document.getElementById("myModal");
// Get the image and insert it inside the modal - use its "alt" text as a caption
var modalImg = document.getElementById("modal-adv-page-img");
var img1 = document.getElementById("adv-page-img-01")
var img2 = document.getElementById("adv-page-img-02")
var img3 = document.getElementById("adv-page-img-03")
var captionText = document.getElementById("caption");
img1.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
img2.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
img3.onclick = function(){
modal.style.display = "block";
modalImg.src = this.src;
captionText.innerHTML = this.alt;
}
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}

You could try this:
$("#myModal").on('shown.bs.modal', function () {
$(this).focus();
});

The autofocus attribute won't work in this case, since this will fire on page load. However, you can easily tackle this problem with some JavaScript.
document.getElementById('modal').focus(); // vanilla JS
$('#modal').focus(); // jQuery
Make sure to trigger one of these functions as soon as the modal is openend.
