When I click on the menu button It is not opening the menu

const menuBtn = document.querySelector('#menuBtn')
const exitBtn = document.querySelector('#exitBtn');
const menu = document.getElementsByClassName('menu');
menuBtn.addEventListener('click' , () => {
menu.style.display = 'block'
})
.fa.fa-bars.menuBtn {
color: #fff;
font-size: 35px;
cursor: pointer;
display: none;
}
.fa.fa-times-circle.exit {
color: white;
font-size: 35px;
cursor: pointer;
}
#media (max-width: 934px) {
.max-width {
padding: 0 50px;
}
.fa.fa-bars.menuBtn {
display: block;
}
.navbar .menu {
position: fixed;
height: 100vh;
width: 100%;
left: 0;
top: 0;
background-color: #111;
text-align: center;

}
.menu{

}
.exit {

}
}

</nav>
How do I make it work ? I tested to see if the add event listener was working and it was working but when it comes to displaying the menu when clicked it does not work. Any idea what the issue may be ? I am not that good at using Javascript so any help would be appreciated . Thank you

document.getElementsByClassName('menu'); doesn't return a single element. It returns an HTMLCollection. So menu isn't an element and menu.style.display = 'block doesn't do what you're trying to do.

document.getElementsByClassName('menu') gets multiple elements, all of which have the class 'menu'. The function returns an HTMLCollection, but you can treat it like a list. If you want to use classes, I would recommend using:
var list = document.getElementsByClassName('menu')
for (var item of list) {
// Do Stuff Here
}
If you have multiple menus, consider using JQuery with the .each(function) method for functions.

Navigation Bar retains class when scrolling despite having a function to remove the class

I'm currently trying to create a navigation bar that sticks when you scroll past. I've gotten to the point where the bar will stick when I scroll past, but when I scroll back to the top the navbar is still sticking. I've been able to troubleshoot to realize that the navbar.offsetTop is being set to 0 when scrolling past, which causes the class "sticky" to never be removed. How can I fix this so that the navbar retains its original offset while being "stuck" to the top of the page?

if (window.scrollY >= navTop) {
navbar.classList.add("sticky");
}
else {
navbar.classList.remove("sticky");
}
}
window.addEventListener('scroll', stickyNav);

The problem is in the function definition of stickyNav.
What I'm seeing is stickyNav function is registered as a callback for the scroll event. But the variables navbar and navTop are inside the function which is assigning values to them every time you scroll. And navTop is getting assigned 0 every time. And the sticky class is never removed.
Try avoiding reassigning values. This worked for me.

CSS delays in changing the visibility of an element from `visible` to `hidden`

I have a navbar that contains three elements. Horizontally, from left-to-right, they are: socialMediaIcons, logoArea, and navBarOptionsList.
I wrote javascript and CSS such that, when the user begins to scroll down the page, the socialMediaIcons and navBarOptionsList's visibility change to hidden.
The problem is, the socialMediaIcons element lags by about half a second to become hidden after the user scrolls down. The navBarOptionsList hides immediately after even slightly scrolling down the page (this is the expected behaviour -- and it is what I'd like the socialMediaIcons to do too).
Below is the CSS (which is where I suspect the problem is), as well as the Javascript (detailing the logic for hiding the two elements) and HTML:

Because there is transition duration set for socialMediaIcon class but for .navBarOptionsList no duration set.

Collapsed sidebar as default

I'm new to web applications, so I don't know HTML, CSS and JS good enough to handle problems by myself yet. I followed some YT tutorial to create collapsible sidebar, but I don't know why it is collapsed as default and i can't make it opened. I think that the problem is that i don't know what exactly is going on in my code. Can you tell me what I'm doing wrong and help me understand how this should work?

JS:
$("#menu-toggle").click(function(e){
e.preventDefault();
$("#wrapper").toggleClass("menuDisplayed");
});

Ok, I'll tell you how to achieve what you want (2 methods) and then I’ll explain how your code works.
method 1
in your first div (#wrapper), add the class menuDisplayed:
<div id="wrapper" class="menuDisplayed">
method 2
you can also change your CSS to do what you want and make the "menu displayed" the default style:
replace "menuDisplayed" with "menuHidden" throughout your code, so that it continues to make sense semantically
update styles for #sidebar-wrapper giving it a value other than 0 for width.
#sidebar-wrapper{
z-index: 1;
position: fixed;
width: 250px;
height: 100%;
overflow-y: hidden;
transition: 0.15s;
background-color: var(--black) ;
font-size: 1em;
}
now change styles for #page-content-wrapper too, so that it leaves room for your sidebar:
#page-content-wrapper{
width: 100%;
position: absolute;
padding: 15px;
padding-left: 250px; /* leaving 250px of space on the left */
transition: 0.15s;
color: black;
}
the next step is to make the closed sidebar have the right styles:
#wrapper.menuHidden #sidebar-wrapper{
width: 0; /* the element of id 'wrapper' and class 'menuHidden' must have width 0 */
}
#wrapper.menuHidden #page-content-wrapper {
padding-left: unset; /* clears the attribute that gave space to the sidebar */
}
now I'll explain how your code works (before you change the sidebar behavior):
your CSS tells the browser that the element with the sidebar-wrapper id should have null width (so it does not appear as soon as you load the page), but it also says that the element with id sidebar-wrapper should be 250px wide when inside another element that has the wrapper id and the menuDisplayed class.
the magic is in your javascript: it tells the browser to toggle the menuDisplay class of the element with id wrapper, which activates the CSS style that makes your sidebar 250px wide, and so it appears. when toggled again, the menuDisplayed class is deleted from the element with id wrapper and your sidebar returns to having width equal to 0.
the $("#menu-toggle").click adds an event listener for the 'click' event using jQuery. when this event is fired (someone clicks in the element with the menu-toggle id), the callback function is executed:
function(e){
e.preventDefault(); // prevents the default behavior of the element (if it is an anchor (<a></a>), it loses the ability to change pages, etc.)
$("#wrapper").toggleClass("menuDisplayed"); // toggles the class 'menuDisplayed' of the element with id 'wrapper'
}

You can add the class menuDisplayed to the navbar (with id #wrapper) initially, so on page load, it will be displayed.
<div id="wrapper" class="menuDisplayed">

you should add the class menuDisplayed to your #wrapper. then it can show by default.
<div id="wrapper" class="menuDisplayed">

Material Components: Keeping Menu "Open" when clicking inside

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?

// e.preventDefault();
// menu.hide();
// });
});
}
$(document).ready(function() {
hoverTabs();
});

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.
