CSS & Javascript issues with a hamburger menu and an image gallery

I was following 2 youtube tutorials while working on a website. One tutorial was on building a complete website that's responsive and the second was on creating an image gallery with a grid layout. The end result that I had when I finished working on my website looked good but I noticed two problems.
When you decrease the size of the website so that it takes up half of your screen, the navbar shrinks down and you get a hamburger menu. But clicking on the hamburger isn't opening it up like it should. There's an eventListener that should be adding and removing a class called active but nothing is happening.
This is the html code that contains the navbar and hamburger icon
<header>
Glitta Art Studio
<div class="bx bx-menu" id="menu-icon"></div>
<ul class="navbar">
<li>Home</li>
<li>About</li>
<li>Gallery</li>
<li>Contact</li>
</ul>
</header>
This is the CSS for the media query
#media(max-width: 1140px) {
section {
padding: 50px 8%;
}
#menu-icon {
display: initial;
color: var(--text-color);
}
header .navbar {
position: absolute;
top: -400px;
left: 0;
right: 0;
display: flex;
flex-direction: column;
text-align: center;
background: #2b2640;
transition: .3s;
}
header .navbar .active {
top: 70px;
}
.navbar a {
padding: 1.5rem;
display: block;
}
.col {
width: 50%;
margin-bottom: 10px;
}
}
And here's the JavaScript
let menu = document.querySelector("#menu-icon");
let navbar = document.querySelector(".navbar");
menu.addEventListener("click", function () {
navbar.classList.toggle("active")
});
window.onscroll = () => {
navbar.classList.remove("active");
};
The second problem is technically not as big of a deal as the nav, but it's been more annoying for me to deal with so far. When you move your mouse over one of the images in the gallery section, a white box appears over the image with a title of the image and some information about it. But for some reason, the person in the tutorial added an a tag to the text in these boxes and I blindly added that to my project without thinking. Clicking on the box brings you back up to the homepage so I want to get rid of that completely and not have it link to anything. I'm not sure what the issue is with the CSS, but if you try to remove the a tags in the html and replace them with a regular p tag then it completely ruins the the grid of images and they all get stuck on one side of the screen.
Here's the HTML code of the gallery (There's 10 divs exactly like this with the same filler text and temporary image)
<div class="image-gallery">
<div class="image-box">
<img src="img/paintbrush.jpeg" alt="paintbrush">
<div class="overlay">
<div class="details">
<h3 class="title">
Painting Title
</h3>
<span class="category">
text about piece here
</span>
</div>
</div>
</div>
<div class="image-box">
<img src="img/paintbrush.jpeg" alt="paintbrush">
<div class="overlay">
<div class="details">
<h3 class="title">
Painting Title
</h3>
<span class="category">
text about piece here
</span>
</div>
</div>
</div>
And here's the CSS
.gallery {
margin: 0;
padding: 0;
position: relative;
}
.image-gallery {
width: 100%;
max-width: 950px;
margin: 0 auto;

opacity: 1;
}
.image-gallery .image-box .details {

}
.image-gallery .image-box .details .title {

font-size: 24px;
font-weight: 600;
position: relative;

opacity: 0;

}
.image-gallery .image-box .details .category {
font-size: 18px;
font-weight: 400;
position: relative;

opacity: 0;
visibility: hidden;

}

}
.image-gallery .image-box .details .title a,
.image-gallery .image-box .details .category a {
color: #222222;
text-decoration: none;
}
Sorry for asking these basic questions. I haven't practiced coding anything in a long while so I've forgotten a lot of things.
Edit: I was able to fix the gallery issue. Now its just the hamburger issue that I have to deal with

You can try implying the function in the HTML element itself like this:
<div class="bx bx-menu" id="menu-icon" onclick="ToggleClassActive()"></div>
and you need to delete the eventlistener function and use this instead
function ToggleClassActive(){
let menu = document.querySelector("#menu-icon");
let navbar = document.querySelector(".navbar");
navbar.classList.toggle("active");
}
You also need to ensure that the script is after the elements(The best place to place your script is right before the
And could you please show the error which occurs in the console

CSS Navbar Transition is Smooth on Scroll Down but no Transition at all on Scroll Back Up

I am currently working on a website with a navigation bar at the top of the screen that is initially transparent when you first visit the site, but turns into a white bar with black text the moment you start scrolling down. It also shrinks a little. It has a really nice and smooth transition as it changes it's color and shrinks, but when you scroll back to the top of the page, there is no more smooth transition but rather an instant ugly transition. Actually the changing of the color back to transparent seems okay but the resize of the bar lacks the transition. I uploaded a GIF so you can see exactly what's the problem.
There is a second problem I would like to ask for. As you can see in the GIF, there is an underline animation on text hover, however, I cannot get it to work on the white navbar. I want that underline to become black, just like the text and shrink with the rest of the navbar.
Here is the GIF:

And the JS:
$(window).on("scroll", function() {
if($(window).scrollTop()) {

}
else {
$('nav').removeClass('scrolled');

})
$(function () {
$(window).scroll(function () {
if ($(this).scrollTop()> 2) {
$('.logo img').attr('src', 'res/logos/main.png');
}
if ($(this).scrollTop() < 2) {
$('.logo img').attr('src', 'res/logos/main_light.png');
}
});
});
And the important HTML:
<header class="index">
<nav class="navbar">
<div class="logo">
<a href="#">
<img class="logoimg" src="res/logos/main_light.png">
</a>
</div>
<div class="menu">
<ul>
<li><a class="current" href="index.html">Home</a></li>
<li>Company</li>
<li>Services</li>
<li>Portfolio</li>
<li>Blog</li>
<li>Contact</li>
</ul>
</div>
</nav>
</header>
Note that .scrolled is the one that changes the navbar once you scrolled. May your road lead you to warm sands!

You're setting the transition for the a elements twice. First as .menu a and then as nav ul li a. The nav bar animates when scrolling up, but the transition lasts 0.1s, as declared for the selector .menu a.
You can either change .menu a to .menu nav ul li a or redesign your classes.
For the underline animation, just add the nav.scrolled selector to the classes you already have, for instance: nav.scrolled .menu a::before and change the background color. You will probably also need to re position the ::before element.

How to create a smooth animated flowing button?

I'm planning to change all the input[type=submit]s & buttons in my website into this smooth animated flowing button.
So, how do I create this using HTML, JavaScript & CSS? Especially I made this GIF to post it in Stack Overflow. And I don't think, I've to post some codes in this question to explain it. :/
EDIT: I don't want exactly Curls effect with bottom right to top left. It should start affecting from the area I click. In the next GIF I've clicked in the middle. Now please see the affect.
I hope you can understand what I mean. It should start flowing to the outside from the exact area I click.

You can use hover.css, Checkout background transition in that
http://ianlunn.github.io/Hover/ .
If you want exactly like the one you posted. you can always try some trial and error with hover.css

you can easily make with simple css see this click

Hope this helps!

Center element with animation / transition

I'm trying to create a full screen menu that does a bottom-to-top movement and I'm having trouble when it comes to vertically centering it.
Basically, it comes out of the screen and should end up right in the middle of it (centered).
However, since it is a fixed menu with an unknown height and I'm using animations, the options available aren't many:
I can't use the margin: auto technique because the auto value doesn't work with transitions;
I'm trying to avoid using flexbox;
translateY() seems to work fine but it creates a top-to-bottom movement instead of the desired bottom-to-top one (see my code)
anything else? (preferably that works with older browsers, but I can also manage with using translateY if there's a way to change the direction)

Notes:
The CSS offset properties (top, bottom, left, right), when applied to absolutely-positioned elements (which includes position: fixed), shift the element x-distance from the respective edge.
You have top: -100% in your code. This puts the element 100% above the top edge.
You then have it shifting to top: 50%. This puts the element halfway inside the container.
Essentially, your animation moves the element a distance of 150%, from above the window to inside it. The movement is top to bottom.
But you want the movement to go from bottom to top.
So start the element all the way at the bottom and off-screen (top: 100%), and have it shift up to halfway inside the container (top: 50%).
The transform: translate() rule simply fine-tunes the centering.
If translateY(-50%) is applied to the primary state (like in your code), it will shift 50% of the nav onto the screen before the transition (demo).
That's why I applied translateY(-50%) only to the transitioned state.

Javascript: Hover over Issues & How can I structure the html efficiently?

I've written a Javascript that triggers upon a person interacting an image, but I have some difficulty tackling the issues that I'm having. Please take a look :)
Heres what the Javascript written is suppose to do:
1) When person opens page, all they see are a collection of images.
2) When the cursor / mouse is hovered over the image 2a) info text fadesIn on the bottom and right (.rotate) of the image, 2b) the grayscale effect lowers from 100% to 10%, and 2c) .detail fadesIn at a fixed position on the bottom right corner of the page.
3) All images are associated with a number. That number is then used so that each image can have its own content & text / position: / color: / etc.
And here are the problems I'm facing with:
1) When an image that has its position set as bottom, it moves up when a curser hovers over it.
2) Upon hovering, when the cursor hovers over the images text, it for some reason repeatedly fadesIn and fadesOut.
3) How can I set the .detail to be positioned to the bottom right of the page for all images?
4) How can the image number (set as .rotate) placed outside of the image and be vertically centered from the images height?

HTML Changes
Take <p class="rotate"> ... </p> out of targetDiv and move it into frontpage-img-wrap
Notes
position:absolute;width:100% solves the bottom positioned div from jumping up on hover
fade in/out effects are done with transition opacity and visibility
easier to debug since you can now for the :hover state in developer tools
The position of rotate is inexact - you may need to calculate image height with JS, then set the rotate div's HEIGHT as the images width

Addressing only your fadeIn/Out issues:
I'd really suggest using pure CSS for this. The JS just complicates it:
.targetDiv { opacity: 0; transition: opacity 0.5s linear; }
.frontpage-img-wrap:hover + .targetDiv { opacity: 1; }
So don't hide() (creates display: none;) your text at all, but just drop opacity to 0, set a transition (for that nice fade effect... make sure to use vendor prefixes with transition), then raise opacity to 1 whenever .frontpage-img-wrap is hovered.
Edit
As far as your bottom-aligned elements: it is because of the $('.targetDiv').hide(); (translated display: none;) that is pops up when hovered... it needs to maintain size. Doing my CSS trick of just turning off the opacity will let the text keep its size. But if you must do it with JS, you need to set the size of the whole .show element so it doesn't resize on hover.
