At a road block with scroll section for my featured items on site

On my site I have a scroll section that will display watches and allow you to scroll on the section similar to what rolex does on their homepage. I created div container for the section and added a wrapper container that I was using to control the items. I also was trying to add arrows that can be used as an option to scroll just like how rolex does on theirs. Nothing is working. The items are there but the functionality isnt. Take a look at Rolex website and scroll down to their watches section on the home page. I want to do exactly that.
I tried adding JavaScript to make it functional but that did nothing for me. I even added a console.log() to see if anything would print in the browser console and got nothing. Please help.
// Select the left and right arrow buttons
const leftButton = document.querySelector('.arrow-button.left');
const rightButton = document.querySelector('.arrow-button.right');
// Select the watch items wrapper element
const watchItemsWrapper = document.querySelector('.watch-items-wrapper');
// Scroll the watch items wrapper element to the left or right when the arrow buttons are clicked
leftButton.addEventListener('click', () => {
watchItemsWrapper.scrollBy({
left: watchItemsWrapper.scrollLeft - 200, // Scroll 200 pixels to the left
behavior: 'smooth' // Use a smooth scroll transition
});
});
rightButton.addEventListener('click', () => {
watchItemsWrapper.scrollBy({
left: watchItemsWrapper.scrollLeft + 200, // Scroll 200 pixels to the right
behavior: 'smooth' // Use a smooth scroll transition
});
});

<!-- End of Watch Reel -->

Add overflow: scroll to your .watch-items-wrapper:
.watch-items-wrapper {
display: flex;
flex-wrap: nowrap;
overflow: scroll;
}
You can remove the overflow: scroll; from your .watch-reel-container, it's not needed. If you want the container to span full width then add overflow: hidden to your .watch-reel-container.
Next adjust both your scroll functions as such:
Left:
leftButton.addEventListener('click', () => {
watchItemsWrapper.scrollBy({
left: -200,
behavior: 'smooth'
});
});
Right:
rightButton.addEventListener('click', () => {
watchItemsWrapper.scrollBy({
left: 200,
behavior: 'smooth'
});
});
I think this will give you the functionality you're looking for.
If you'd like to hide the scrollbar but keep the functionality, check our this doc from w3schools.
I hope this helps!

on click div get big and back to normal

I created a mini Qcm, when I click on an answer the check moves on the div on which I clicked
const reps = document.getElementsByClassName('rep');
[].forEach.call(reps, function(rep) {
$(rep).click(function() {
if (!rep.querySelector('.check')) {
[].forEach.call(reps, function(repToDel) {
if (repToDel.querySelector('.check')) {
repToDel.querySelector('.check').remove()
}
})
$(rep).last().append('<div class="check"><object data="check.svg" width="20" > </object></div>')
}
})
})
.container {
padding: 5%;
display: grid;
gap: 20px;

but when I click the div get big and back to normal at the same time,I tried the overflow:hidden, but it didn't work.
the change between the check must be done smoothly.

With this JQuery code and if the image is present it's works
$(function(){
const reps = document.getElementsByClassName('rep');
[].forEach.call(reps,function(rep){
$(rep).click(function(){
// Remove Check Div only for Old Check
[].forEach.call(reps,function(repToDel) { if(repToDel.querySelector('.check')) repToDel.querySelector('.check').remove(); });
// Put Check Div for New Check
if(! rep.querySelector('.check')) $(rep).last().append('<div class="check"><object data="check.png" width="20" > </object></div>');
});
});
});

How to cancel the increase of each next value in the for loop by the previous one (Making a slider)

I want to make a simple slider that will work by shifting position:right
I need to shift each picture by 250px, doing it through a cycle - the first picture shifts as needed, and all the others increase on each other, and go much further. Is it possible to somehow set the same indentation values in 250px to all elements in the loop?

Sticky section scrolling effect HTML

In the following pen I would like to create an effect where you have to scroll (by scrolling, not with mouse movement), all the way down until the top image is revealed, until we move to the next section.
The effect I'm trying to re-create, in case the explanation is too confusing can be found on Apple's website here
As you scroll down you'll understand.
let wrapper = document.querySelector('#wrapper');
let topLayer = wrapper.querySelector('.top');
let handle = wrapper.querySelector('.handle');
wrapper.addEventListener('mousemove', e => {
handle.style.top = e.clientY + 'px';
topLayer.style.height = e.clientY + 'px';
});
});

Here is an example using the CSS position: sticky
body {
font-family: georgia;
height: 1000px;
}
img {
display: block;
margin: 0 auto;
}
.sticky {
position: sticky;
position: -webkit-sticky;
width: 100%;
top: 25vh;
justify-content: center;
align-items: center;
color: #fff;
}
.wrapper {
width: 75%;
margin: auto;
background-color: silver;
padding: 15px;
}
.wrapper {
height: 200vh;
}

Add image below a certain class of element using css

What I want to do:
I want to add a "walkingMan" image under an element when its class is changed to activeCell. I know how to do it when the image is added to the front or back of the element using pseudo class, but as far as I know, there isn't something like :below that I can use to achieve the same effect. Is there a way in css I can use to micmic this?
What I have done:
I have added image below every upper cell and make it visible when the class is changed to activeCell. But I hope to find a more simple solution.
What it looks like:
Code: Simplified Code Example

You can use a single pseudo element on the .cell element and place a background image on it when it's active.
let activeIndex = 0;
const cells = [...document.querySelectorAll('.cell')];
setInterval(() => {
cells.forEach(cell => {
cell.classList.remove('activeCell')
});
cells[activeIndex].classList.add('activeCell');
activeIndex = activeIndex === cells.length - 1 ? 0 : (activeIndex + 1);
}, 300)
.cell {
display: inline-block;
border: 1px solid black;
margin-bottom: 1.2em;
}
.activeCell {
background-color: lightgrey;
position: relative;
}
.activeCell::after {
content: "";
position: absolute;
width: 1em;
height: 1em;
top: 1.3em;
left: calc(50% - .5em); /* Center the stickman. Position it half of its width before the parent center*/
background-image: url('https://www.shareicon.net/data/512x512/2016/01/17/704754_people_512x512.png');
background-size:cover; /* Scale the stickman to completely cover the background area. */

I've never been a fan of the ::before and ::after pseudo classes mainly because I've personally noticed some oddities when trying to position things in Chrome vs IE (damn it IE!). Since most people here are going to give a solution using these pseudo classes (because that's somewhat what you asked) I thought I'd give a different solution using flexbox and more divs.
Not the most optimal for download size but I do like that it's not absolute positioning elements and if the squares get bigger or smaller it's pretty easy to handle that as a scss variable at the top of the file. This all uses only two values, your padding between boxes and the size of the boxes so it should be easy to update and maintain.
Anyway, have fun! Awesome question by the way :-)
.blocks {
display: flex;
}
.block {
flex: 0 0 20px;
margin: 0px 5px;

flex-direction:column;

flex: 0 0 20px;
margin: 5px 0px;
background: grey;
}

<div class="block"><div class="square"></div></div>
<div class="block"><div class="square"></div></div>
<div class="block"><div class="square"></div></div>
</div>

Using jQuery you can toggle the class upon clicking with this:
$('.cell').click(function() { //catch clicks on .cell
$('.cell').removeClass('activeCell'); //remove class "activeCell" from all
$(this).addClass('activeCell'); //add class "activeCell" to .cell clicked
});
Apply position: relative; to .top and .bottom:
.top,
.bottom {
position: relative;
}
And use the psuedoclass :before to create a image under the .activeCell
.activeCell:before {
content: "";
position: absolute;
bottom: -20px;
height: 20px;
width: 20px;
background-image: url("https://www.shareicon.net/data/512x512/2016/01/17/704754_people_512x512.png");
background-size: 20px 20px;
}
And remove this:
.walkingMan {
width: 20px;
height: 20px;
display: inline-block
}
And this:
<img src="https://www.shareicon.net/data/512x512/2016/01/17/704754_people_512x512.png" alt="walkingMan" class='walkingMan'/>
And to add space between the divs .top and .bottom put a <br> between them.
$('.cell').click(function() {
$('.cell').removeClass('activeCell');
$(this).addClass('activeCell');
});
.cell {
display: inline-block;
border: 1px solid black;
cursor: pointer;
}
.top,
.bottom {
position: relative;
}
.activeCell {
background-color: lightgrey;
}
.activeCell:before {
content: "";
position: absolute;
bottom: -20px;
height: 20px;
width: 20px;

You can do something like this, using CSS only. With :target selector you can apply a style to the element you need to hide / show.
.container {

}
.link {

display: block;

}
#p3:target {

}
#p4:target {

}
height: 90px;

}
.walking-man img {

display: block;
}
