Created Modal displays after click, then removes itself again

I created 2 Modals.The first modal, which is class = "modal" appears as it should when add button is clicked, but when I click the "+" sign on the form to display the next Modal which is the class = "category-modal that modal goes back to display none for some reason.
I made a runable code:
//get HTML elements username
let arrow = document.querySelector(".next");
let profSetting = document.querySelector(".prof-settings ul");
let asset = document.querySelector(".nav-side-asset");
//click event for username drop-down
arrow.addEventListener("click", () => {
arrow.classList.toggle('rotate-90');
profSetting.classList.toggle('transform');
asset.classList.toggle('position');
modal.classList.toggle('modal-position');
});
//get HTML elements assets
let arrowAsset = document.querySelector(".next-asset");
let assets = document.querySelector(".assets ul");
//click event for asset drop-down
arrowAsset.addEventListener("click", () => {
arrowAsset.classList.toggle('rotate-90');
assets.classList.toggle('transform');
})
//Generate tag ID
//get HTML elements modal
let modal = document.querySelector(".modal");
let addbtn = document.querySelector(".add-button");
let close = document.querySelector(".close");
let background = document.querySelector(".greyback")
//click event for modal pop up
addbtn.addEventListener("click", () => {
modal.style.display = "block";
genID()
background.style.display = "block";
})
//click event for modal remove itself
close.addEventListener("click", () => {
modal.style.display = "none";
})
function genID() {
let minNum = 0;
let maxNum = 1000;
let randomNum = Math.floor(Math.random() * (maxNum + 1) + minNum)
document.querySelector(".id").innerHTML = randomNum;
}
//get modal for category and department
let categoryModal = document.querySelector(".category-modal");
let categoryAdd = document.querySelector(".category-add");
let cancel = document.querySelector(".cancel");
categoryAdd.addEventListener("click", () => {
categoryModal.style.display = "block";
})

I have attached a screenshot on what buttons to press to get to the issue:

I installed the code you have given and played with it. I noticed that the issue you are facing is due to the page being refreshed, the normal behaviour when you click on a button inside a form, which you can prevent with e.preventDefault(). For categoryAdd as an example:
categoryAdd.addEventListener("click", (e) => {
e.preventDefault();
categoryModal.style.display = "block";
});
Add e.preventDefault() for each button that don't need to refresh the page, after passing the event e as parameter like I did above.

Problems with legend tag when I am unhiding and re-hiding it in a fieldset

So I am trying to do this thing where a legend tag shows when the input box is being clicked. The idea is there is that the input box is inside a fieldset and the legend as a hidden class first. If the input box is on focus or clicked, the hidden class will be removed and it will show like this
I also added a part wherein if was left blank the legend tag will disappear by re-adding the removed
hidden class. However, it also leaves awkward whitespace in a place where it is formerly was like this
Did I do something wrong? Is there something I must do first?
The code is here:
$(function() {
$(".next").click(function() {
var div = $(this).closest('.wrapper');
var next = $(this).closest('.wrapper').next();
div.addClass('hidden');
next.removeClass('hidden');
})
})
$(function() {
$('input').click(function() {
$('input').each(function(index) {
const legend = $(this).closest('fieldset').children('legend');
if (($(this).val() == "" || $(this).val() == " ") && $(this).is(":focus") == false) {
if (legend.hasClass('hidden') == false) {
legend.addClass('hidden');
$(this).css("margin-top", "10px");
}
} else {
legend.removeClass('hidden');
$(this).css("margin-top", "-150%");
}
})
})
})

How to show the next div and hide the previous one?

New to Javascript, I'm working on a quiz like solution that uses divs and buttons to cycle through the questions. I have written some code in Javascipt but for some reason It doesn't go through the last question where it should stop. Any help will be appreciated on why the next doesn't go to the last question.
var question = document.querySelectorAll('.question');
var next = document.getElementById("next");
next.addEventListener("click", function() {
var question = document.querySelectorAll(".question");
for (var i = 0; i < question.length; i++) {
if (question[i].style.display != "none") {
question[i].style.display = "none";
//resets to original questions
if (i == question.length - 1) {
question[0].style.display = "block";
} else {
question[i + 1].style.display = "block";
}
break;
}
}
});
.question {
margin: 50px;
width: 300px;
height: 300px;
border-radius: 10px;
padding: 50px;
text-align: center;
color: white;
background: #333;
position: relative;
display: none;
}
.visible {
display: block;
}
.q-input,
.move {
margin: 10px;
border: none;
padding: 10px;
}
.move {
display: flex;
justify-content: space-between;
}
.move button {
padding: 5px;
font-size: 16px;
width: 60px;
border-radius: 5px;
border: none;
cursor: pointer;
transition: 0.4s;
}
.move button:hover {
box-shadow: -2px -2px 20px #fff;
}
.move button:focus {
outline: none;
}
<div class="question visible">
<h1>Question <span class="one">1</span></h1>
<p>What is your Name</p>
<input type='text' class="q-input">
<div class="move">
<button id="prev">Prev</button>
<button id="next">Next</button>
</div>
</div>
<div class="question">
<h1>Question 2</h1>
<p>What is your Age</p>
<input type="text" class="q-input">
<div class="move">
<button id="prev">Prev</button>
<button id="next">Next</button>
</div>
</div>
<div class="question">
<h1>Question 3</h1>
<p>What is your Sex</p>
<input type="text" class="q-input">
<div class="move">
<button id="prev">Prev</button>
<button id="next">Next</button>
</div>
</div>

You are using document.getElementById("next") which only returns the first button with an ID of next, so only that button gets the click listener added to it.
IDs are meant to be just one unique element, so you should use class instead - change it to <button class="next">Next</button>
In your JS you should select all these next button elements, and use forEach to add a listener to all of them.
Then within that listener, you can get the connected question divs to show/hide by using parentElement and nextElementSibling, and check the next element is a question before changing the visibilities.
Also adding/removing the visible class is neater and easier to debug than trying to edit the style property manually.
All together that looks like:
var nextButtons = document.querySelectorAll('.next');
nextButtons.forEach(nextButton =>
nextButton.addEventListener("click", function() {
var currentQuestion = nextButton.parentElement.parentElement;
var nextElement = currentQuestion.nextElementSibling;
if (nextElement.classList.contains("question")) {
nextElement.classList.add("visible");
currentQuestion.classList.remove("visible");
}
}));
.question {
margin: 50px;
width: 300px;
height: 300px;
border-radius: 10px;
padding: 50px;
text-align: center;
color: white;
background: #333;
position: relative;
display: none;
}
.visible {
display: block;
}
.q-input,
.move {
margin: 10px;
border: none;
padding: 10px;
}
.move {
display: flex;
justify-content: space-between;
}
.move button {
padding: 5px;
font-size: 16px;
width: 60px;
border-radius: 5px;
border: none;
cursor: pointer;
transition: 0.4s;
}
.move button:hover {
box-shadow: -2px -2px 20px #fff;
}
.move button:focus {
outline: none;
}
<div class="question visible">
<h1>Question <span class="one">1</span></h1>
<p>What is your Name</p>
<input type='text' class="q-input">
<div class="move">
<button class="prev">Prev</button>
<button class="next">Next</button>
</div>
</div>
<div class="question">
<h1>Question 2</h1>
<p>What is your Age</p>
<input type="text" class="q-input">
<div class="move">
<button class="prev">Prev</button>
<button class="next">Next</button>
</div>
</div>
<div class="question">

<p>What is your Sex</p>
<input type="text" class="q-input">
<div class="move">
<button class="prev">Prev</button>

</div>

It's not possible that more than 1 element has the same id (button next + prev), so changed to class='next' or use unique id's.
You need forEach of your button an eventListener. You can use forEach to iterate over it.
var question = document.querySelectorAll('.question');
var next = document.querySelectorAll(".next");
next.forEach(n => {n.addEventListener("click", function() {
var question = document.querySelectorAll(".question");
for (var i = 0; i < question.length; i++) {
if (question[i].style.display != "none") {
question[i].style.display = "none";
//resets to original questions
if (i == question.length - 1) {
question[0].style.display = "block";
} else {
question[i + 1].style.display = "block";
}
break;
}
}
})});
.question {
margin: 50px;
width: 300px;
height: 300px;
border-radius: 10px;
padding: 50px;
text-align: center;
color: white;
background: #333;
position: relative;
display: none;
}
.visible {
display: block;
}
.q-input,
.move {
margin: 10px;
border: none;
padding: 10px;
}
.move {

Web development implementing the form onclick event

I made this log-in and register form in which an onclick submit button of the form its display which form is submitted, left or right to implement it. I have used onclick property and passed a function to it fun() which has one parameter of the type no. So I used two functions fun(0) and fun(1) used to display a message which forms submitted by the user but it does not display the message.
And also I have a problem with the CSS it's not scaling according to the screen size as I used bootstrap for CSS and try the width, position property scale in % but then also it's not working.
function fun(Number n) {
if (n === 1) {
document.getElementsByClassName('m1').style.display = 'none';
} else {
document.getElementsByClassName('m2').style.display = 'none';
}
document.getElementsByClassName('modal').style.display = 'flex';

How to validate a multiple step form

I not able to validate a multiple step form - I want a validation for each field instead of now it validates sets of fields
My code
function show_next(id, nextid, bar) {
var ele = document.getElementById(id).getElementsByTagName("input");
var error = 0;
for (var i = 0; i < ele.length; i++) {
if (ele[i].type == "text" && ele[i].value == "") {
error++;
}
}
if (error == 0) {
document.getElementById("account_details").style.display = "none";
document.getElementById("user_details").style.display = "none";
document.getElementById("qualification").style.display = "none";
$("#" + nextid).fadeIn();
document.getElementById(bar).style.backgroundColor = "#38610B";
} else {
alert("Fill All The details");
}
}
function show_prev(previd, bar) {
document.getElementById("account_details").style.display = "none";

Here is a version that will not go to the next page if there are errors
Let me know what you think
I added two validations. You can change the rest. The code is vastly simplified
function isEmail(str) { // simple email validation
return /(.+)#(.+){2,}\.(.+){2,}/.test($.trim(str));
}
function isEmpty(str) { // test for empty string
return $.trim(str) === "";
}
function validate($div) { // validates any div - will not let you leave the div if error
var $fields = $div.find("input"), hasError = false;
$fields.each(function() {
$(this).removeClass("error")
hasError = this.name=="pword" && isEmpty(this.value);
if (hasError) {
$("#pword").addClass("error").focus();
return false;
}
hasError = this.name=="email" && (isEmpty(this.value) || !isEmail(this.value));
if (hasError) {
$("#email").addClass("error").focus();
return false;
}
hasError = isEmpty(this.value); // the rest of the fields
if (hasError) {
$(this).addClass("error").focus();
return false;
}
})
return hasError?false:true;
}
$(function() {
// validate all divs on submit, but actually only necessary to validate thediv the submit is on
$("#myForm").on("submit",function(e) {
$(".page").each(function() {
if (!validate($(this))) {
e.preventDefault(); // stop submission
return false;
}
});
});
$(".nav").on("click", function() {
var $parent = $(this).closest("div");
var $nextDiv = $(this).hasClass("next") ? $parent.next() : $parent.prev();
if (validate($parent)) { // is the div this button is on valid?
$parent.fadeOut(function() { // fade it out and fade the next one in
if ($nextDiv.length) {
$nextDiv.fadeIn()
for (var i=$(".page").length;i> $nextDiv.index(); i--) {
$("#bar" + i).css({"background-color": "#D8D8D8"}); // we are going backwards
}
$("#bar" + $nextDiv.index()).css({"background-color": "#38610B"});
}
});
}
});
