I created three active links using CSS and javascript. I have three data sets in forms of image that I want to show based on which link is active. The images will be below the link in form of swiper slides. How I do this? My reference for this is the active slide on new balances website

I would create a container to hold the contents of each slide and link buttons to a slide using a data attribute. When a button is clicked, you can remove the active class of the previous slide and add a new one for the current slide. Here is the relevant code that I added with a Codepen link at the bottom.
<div class="active-link" id="active-link">
<li>
<a class="button" data-slide="slide-container-1">1</a>
</li>
<li>
<a class="button active" data-slide="slide-container-2">2</a>
</li>
<li>
<a class="button" data-slide="slide-container-3">3</a>
</li>
</div>
<div class="slide-containers">
<div id="slide-container-1" class="slide-container">
Slide Container 1
</div>
<div id="slide-container-2" class="slide-container">
Slide Container 2
</div>
<div id="slide-container-3" class="slide-container">
Slide Container 3
</div>
</div>
.slide-container {
position: relative;
// I'm not sure what you're looking for visually so I just used a top position greater than what you're already using on the buttons.
top: 14rem;
display: none;
}
.slide-container.active {
display: block;
}
const resetSlideContainers = () => {
[ ...document.querySelectorAll('.slide-container') ].forEach((slide) => slide.classList.remove('active'));
}
for (var i = 0; i < btns.length; i++) {
btns[i].addEventListener('click', function(e) {
removeClass('.button', 'active')
this.classList.toggle('active');
resetSlideContainers();
document.getElementById(this.getAttribute('data-slide')).classList.add('active');
})
}
Here is a working example.

As the title states, I'm making a tabbed section to switch content upon click which works fine, how can I make it so upon clicking a new tab it has a smooth transition to the content as well as prevent jumping to the top of the page every time I click a tab?
I've tried adding the function which prevents it for links but this isn't a link so that doesn't seem to be working.

Here is a simple example using a opacity transition but you can use height, width or transform if you would like. I use aria-attributes to keep track of things like which article is open and if the information in the article should be picked up by screen readers. The two most important CSS classes are show and hide. These control the opacity and when the transition takes place. Show has a slight delay so it waits for the one being hidden to get out of the way. As far as the JavaScript.
Select all the buttons that have popups.
Create a event listener to handle the click.
Select the controlled article and all the articles.
Check if the controlled article is currently hidden.
If it is hide all the artiles.
Change all the buttons aria-expanded attributes to false.
Set the aria-expanded attribute on the clicked button to true.
Set aria-hidden class on the controlled article to false.
Remove the hide class and add the show class to the controlled article.
const buttons = document.querySelectorAll("[aria-haspopup=true]")
const handleClick = (event) => {
const controls = event.target.getAttribute("aria-controls"),
controlled = document.getElementById(controls),
articles = document.querySelectorAll("article");
if (controlled.getAttribute("aria-hidden") === "true") {
articles.forEach(article => {
article.setAttribute("aria-hidden", "true");
article.classList.add("hide");
article.classList.remove("show");
})
buttons.forEach(button => button.setAttribute("aria-expanded", "false"))
event.target.setAttribute("aria-expanded", "true");
controlled.setAttribute("aria-hidden", "false");
controlled.classList.remove("hide");
controlled.classList.add("show");
}

button.addEventListener("click", handleClick);

I wanna have an animated Dropdown-menu as a Navigation!
In Css I've set transition height to 1s and in Javascript I add a value
of for the height property in an Eventlistener. When the ham-symbol is
clicked the menu should go down in a transition of 1s. The problem is that when I click the ham-symbol it does't move with transition...it just appears... I recently found out when I add display: block in the css dropdown menu it works, but then obviously the toggle click ham-symbol doesnt work anymore! Please help!
<nav>

#dropdown {
/* display: block */
border-top: 3px solid red;
position: absolute;
width: 80%;
top: 100%;
left: 10%;
height: 0;
background: #fff;
padding-top: 2.2rem;
box-shadow: 0 2px 2px lightgrey;
z-index: 1;
transition: height 1s;
}
let menu = document.getElementById('ham');
let nav = document.getElementById('dropdown');
menu.addEventListener('click', function(e) {
nav.classList.toggle('hide-mobile');
nav.style.height = "400px";
})
Take a look at this codepen.
You can make it better but your basic requirement is met.
You just needed to:
toggle the height, not the top.
set overflow-y: hidden;
If you want to keep your solution you can try something like that :
let menu = document.getElementById('ham');
let nav = document.getElementById('dropdown');
var isOpen = false;
menu.addEventListener('click', function(e) {
if (isOpen == false){
nav.classList.toggle('hide-mobile');
nav.style.top = "-100%";
isOpen = true;
}
else{
nav.classList.toggle('hide-mobile');
nav.style.top = "0%";
isOpen = false;
}
})
#dropdown {
border-top: 3px solid red;
position: absolute;
width: 80%;
top: 0;
left: 10%;
background: #fff;
padding-top: 2.2rem;
box-shadow: 0 2px 2px lightgrey;
z-index: 1;
transition: 1s;
}
/* Just for the example */
img{
height: 50px;
width: 50px;
margin-left:-5px;
margin-top:-5px;
}
<nav>
<a href="#">
<img id="ham" alt="toggle menu" src="https://static.thenounproject.com/png/195031-200.png">

</li>
<li>

</li>
<li>

</li>
</ul>
</div>
</nav>
Click on "Run code snippet" to see the animation. If that does not work there is definitely a problem with your browser display, try on another machine and check that javascript is not disabled.

MATERIAL COMPONENTS FOR THE WEB (MENUS)
This question is in relation to the Menu Component:
I've modified the code so that the menu opens when hovered instead of clicked. I'm now trying to make the menu stay open or closed when certain elements inside the menu are clicked on..But I'm having trouble getting it to work.
Can anyone help?

When <li class="wont-close"> is clicked, the menu won't close. menu.show();
When <li class="will-close"> is clicked, the menu will close. menu.hide();

When in doubt, create a pure CSS solution...
I'm not accepting my answer as THE ANSWER because this is a hack.
I just want to include this here to show my quick fix that does the exact same thing (right on down to the cubic-bezier animation).
NOTE: I'm still using the Material Design Styles it ships with... Just not any of the JS.

I'm trying to create a pretty basic mobile drop-down menu that expands on click for the top-right nav of this codepen portfolio page project for Free Code Camp. The menu never shows up, but when I inspect the element it seems like the javascript function is actually working, with the "show" CSS class being added and removed to the mobileNavDrop div.
The invisible menu also seems to be located on the page where it's supposed to be, as can be seen in this screenshot using the inspect element tool:
Invisible drop-down menu highlighted with inspect element tool
I've tried pushing it all the way forward with z-index and making the banner invisible to see if it's hiding behind things, but it isn't. I even tried just having the menu start as visible rather than with "display: none;" and it still doesn't show up on the page.
The advice I've gotten elsewhere is to just use jquery and bootstrap, but I'd hoped to understand things more by trying to just write everything from scratch. So it's possible something I wrote for the responsive layout is conflicting?
Here's at least the sections of code that I thought would be relevant. Thanks!

You need:
.show {
display: block;
position: absolute; /* add this line, */
top: 0; /* and this one */
}
Plus, make sure the overflow is visible in every container of that nav that might not be large enough to contain the drop-down menu.
You are probably not seeing the icon because you have not included the FontAwesome library for the icon (fa fa-bars).

In your javascript. I added an else statement so it toggles back and forth.
Your statement only removes 'show' but does not add it back.
I'm trying to create an image slider with controls "Next" and "Previous". Next should slide the image left using a negative margin-left property so as to reveal the second image. All the list elements holding individual images are set to display: inline-block so each list element can stand next to each other instead of stacking.
However, I found out that when the first image slides left it still reveals a little out of it while showing the second image, on and on and on like that, everything slides but never fully. the distance they slide is equal to the width of the image.
Also, when I get to the last image and click on next it should go back to the first image, the problem is that it displays each image along the way to the first image.
window.onload = function () {
var nextBtn = document.getElementsByClassName("nextBtn")[0],
prevBtn = document.getElementsByClassName("prevBtn")[0];
var i = 0;
var imgList = document.querySelectorAll(".slide");
var slideLength = imgList.length;
var lastchild = imgList[slideLength - 1];
nextBtn.addEventListener("click", Next, false);
prevBtn.addEventListener("click", Previous, false);
function Next() {
console.log(slideLength)
imgList[i].style.marginLeft = "-600px";
if (imgList[i].classList.contains("active")) {
imgList[i].classList.remove("active");
}
if (imgList[i] !== lastchild) {
i++;
}
else if (imgList[i] === lastchild) {
i = 0;
for (var j = 0; j < slideLength; j++) {
imgList[j].style.marginLeft = "0";
}
}
imgList[i].classList.add("active");
}
function Previous(e) {
console.log(i);
if (i !== 0) {
imgList[i - 1].style.marginLeft = "0";
i--;
console.log(i);
}
else {
console.log(i);
}
}
}

How can I make this work well strictly with vanilla javascript? Here is the link to the jsfiddle . However, it doesn't seem to work at all there.
Reference : https://jsfiddle.net/a2bk4bwu/3/
Replace your CSS with lines with the for ul & li
ul{
width: 100%;
height: 350px;
border: solid 3px white;
margin:100px auto;
overflow: hidden;
padding-left: 0;
font-size: 0px;
}
li{
font-size : 20px;
display:inline-block;
position: relative;
transition: all 1s cubic-bezier(1,-0.01, 0, 1.13);
list-style: none;
}
Things to note :
'Ul' was taking extra padding by default {webkit-padding-start: 40px}
"display : inline-block" items are dependent on "white-space". So give "0px" to the parent element to remove that white space between slides.
These will fix your CSS issues.
