How to change the background of navbar as you scroll using react?

I am making a website. So, here is my code:
#import url("https://fonts.googleapis.com/css?family=Poppins:100,100i,200,200i,300,300i,400,400i,500,500i,600,600i,700,700i,800,800i,900,900i&subset=devanagari,latin-ext");

As you can see, I have made a navbar. It is transparent. But the thing is, I want it to change color to white as the user scrolls down after a specific div. You can make it white by adding <div class="navigation-wrap bg-light start-header start-style"> I have no idea how to implement this. I have seen some stackoverflow answers, but none of them work.
Thanks in advance.

I only added javascript in your code everything else is same
Steps I took:
Added a scroll event listner to your html.
Wrote a condition to replace the class name of your element if the vertical scroll amount is greater than 50px.
If not then replace and set your class name to default. (helps when you scroll back to top)
window.addEventListener('scroll', navScroll);
//adding scroll event listner
function navScroll() {
if (window.scrollY > 50) {
// Replace all classes from element after 50px of scroll
document.getElementById("myNav").className = "navigation-wrap bg-dark start-header start-style";
} else {
document.getElementById("myNav").className = "navigation-wrap start-header start-style";
}
}

transition between expanding elements

I have another question.
I hope it does not count as dumb question again. most beginner questions seem to been seen as dumb.
Anyway I am trying to have the transition between clicking cards more smooth.
Currently you can click on a card and it expands down and it is smooth when you click on the same card, but if you click on one card then a diferent one it is not smoth expanding the elements.
Mostly when the cards are next to each other in full screen
var $cell = $(".card");
//open and close card when clicked on card
$cell.find(".js-expander").click(function (e) {
e.stopImmediatePropagation();
var $thisCell = $(this).closest(".card");
if ($thisCell.hasClass("is-collapsed")) {
$cell.not($thisCell).removeClass("is-expanded").addClass("is-collapsed");
//$cell.not($thisCell).removeClass('is-expanded').addClass('is-collapsed').addClass('is-inactive');
$thisCell.removeClass("is-collapsed").addClass("is-expanded");
// if ($cell.not($thisCell).hasClass("is-inactive")) {
// //do nothing
// } else {
// //$cell.not($thisCell).addClass('is-inactive');
// }
} else {
$thisCell.removeClass("is-expanded").addClass("is-collapsed");
$cell.not($thisCell).removeClass("is-inactive");
}
});
$cell.find(".card__expander").click(function (e) {
e.stopImmediatePropagation();
});
//close card when click on cross
$cell.find(".js-collapser").click(function () {
var $thisCell = $(this).closest(".card");
$thisCell.removeClass("is-expanded").addClass("is-collapsed");
$cell.not($thisCell).removeClass("is-inactive");
});

A little timeout value will help.
First I check to see if there are any expanded and set a timeout MS number:
let timeout = $('.is-expanded').length > 0 ? 200 : 0
If there is something expanded, the timeout will be 200 miliseconds.
Then we set the expanding element in a timeout, which will be zero if there is nothing currently expanded:
setTimeout(() => {
$thisCell.removeClass("is-collapsed").addClass("is-expanded");
}, timeout)
You can adjust the timeout value
var $cell = $(".card");
//open and close card when clicked on card
$cell.find(".js-expander").click(function(e) {
e.stopImmediatePropagation();
var $thisCell = $(this).closest(".card");
if ($thisCell.hasClass("is-collapsed")) {
let timeout = $('.is-expanded').length > 0 ? 200 : 0
$cell.not($thisCell).removeClass("is-expanded").addClass("is-collapsed");
//$cell.not($thisCell).removeClass('is-expanded').addClass('is-collapsed').addClass('is-inactive');
setTimeout(() => {
$thisCell.removeClass("is-collapsed").addClass("is-expanded");
}, timeout)
// if ($cell.not($thisCell).hasClass("is-inactive")) {
// //do nothing
// } else {
// //$cell.not($thisCell).addClass('is-inactive');
// }
} else {
$thisCell.removeClass("is-expanded").addClass("is-collapsed");
$cell.not($thisCell).removeClass("is-inactive");
}
});
$cell.find(".card__expander").click(function(e) {
e.stopImmediatePropagation();
});
//close card when click on cross
$cell.find(".js-collapser").click(function() {
var $thisCell = $(this).closest(".card");
$thisCell.removeClass("is-expanded").addClass("is-collapsed");
$cell.not($thisCell).removeClass("is-inactive");
});

Nested drop down menu using w3schools method

I had designed a menu using this link.
Now I have problem on using nested drop down links.
I had treid several ways but because I'm not using standard ul and li tags now I have problem to fix this issue.
Here I will copy my code so you can see what I'm doing and also I had attached some screenshots.
jQuery(".search-form-header-icon").click(function () {
jQuery(".header-search-form-input").toggle('fast', function () {
if (jQuery(this).css("display") == "block")
jQuery(this).css('display','inline-block');
});
});
jQuery(window).on('scroll', function () {
var s = jQuery(window).scrollTop(),
d = jQuery(document).height(),
c = jQuery(window).height();
var scrollPercent = (s / (d - c)) * 100;
var pagePercent = Math.round(scrollPercent)
var gradient_bar_header_width = pagePercent + "%"
jQuery(".gradient-bar-header").css("width", gradient_bar_header_width);
});
/* Toggle between adding and removing the "responsive" class to topnav when the user clicks on the icon */
function menu_function() {
var x = document.getElementById("myTopnav");
if (x.className === "topnav") {
x.className += " responsive";
} else {
x.className = "topnav";
}
}

Now it looks like this:
I want to be like this one:
How can I add nested menu items?

Talking about nested drop-downs, consider using nested lists.
Here you go!. I just wrapped the <a> inside the dropdown-content into a list item.
Try this.
jQuery(".search-form-header-icon").click(function () {
jQuery(".header-search-form-input").toggle('fast', function () {
if (jQuery(this).css("display") == "block")
jQuery(this).css('display','inline-block');
});
});
jQuery(window).on('scroll', function () {
var s = jQuery(window).scrollTop(),
d = jQuery(document).height(),
c = jQuery(window).height();
var scrollPercent = (s / (d - c)) * 100;
var pagePercent = Math.round(scrollPercent)
var gradient_bar_header_width = pagePercent + "%"
jQuery(".gradient-bar-header").css("width", gradient_bar_header_width);
});
/* Toggle between adding and removing the "responsive" class to topnav when the user clicks on the icon */
function menu_function() {
var x = document.getElementById("myTopnav");
if (x.className === "topnav") {
x.className += " responsive";
} else {
x.className = "topnav";
}
}

How do I make the Drop down Button work html css

So im creating a website and I have it so when the width of the window is smaller then 768px then the navbar collapses. The navbar collapses but does not show the the individual items on navbar. The nav bar collapse is a vertical navbar. I am using Bootstrap By the way. So to sum it all up I have a vertical menue/navigation bar yet I am having trouble with getting the dropdowns to open.
here is my html:
-->
<header id="home">
<!-- Background Image -->
<div class="bg-img" style="background-image: url('./img/background1.png');">
<div class="overlay"></div>
</div>
<!-- /Background Image -->
<!-- Nav -->
<nav id="nav" class="navbar nav-transparent">
<div class="container">
<div class="navbar-header">
<!-- Logo -->
<div class="navbar-brand">
<a href="index.html">
<img class="logo" src="img/Logo.png" alt="logo">
<img class="logo-alt" src="img/Logo.png" alt="logo">
</a>
</div>
<!-- /Logo -->
<!-- Collapse nav button -->
<div class="nav-collapse">
<span></span>
</div>
<!-- /Collapse nav button -->
</div>

Now, that's a Bootstrap 4 navbar with dropdown:

My Pop Up Window isn't displaying right

I'm redesigning a website for fun. I have a pop up window that opens up after you click a button. However, the window and button shows up in a weird layout. The button is displayed to the far left and the text is all over the screen. You can actually see the entire code on codepen: http://codepen.io/sibraza/pen/wWgqBO
Here is the HTML:
<!--- This is what the user see when they click the button -->
<span class="msg"><button class="btn btn-danger"data-js="open">Subscribe to our Newsletter</button></span>
</section>
<!-- this is what the user sees when the popup is displayed -->
<div class="popup">
<h2>Subscribe to the Newletter:</h2>
<button name="close">Close Pop-up</button>
</div>
Here is the CSS:
button {
font-family: "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;
background: lightcoral;
border: 0;
border-radius: 4px;
padding: 7px 15px;
font-size: 16px;
color: #FFFFFF;
cursor: pointer;
}
button:focus {
outline: none;
}
button:hover {
background: #f39797;
}
.popup {
background: rgba(255, 255, 255, 0.8);
position: fixed;
display: none;
z-index: 5000;
height: 100%;
width: 100%;
left: 0;
top: 0;
}
.popup > div {
border-radius: 4px;
position: fixed;
background: #FFFFFF;
box-shadow: 0px 0px 12px #666666;
padding: 30px 15px;
/* Width of popup can be changed */
width: 80%;
max-width: 600px;
z-index: 5001;
-webkit-transform: translate(-50%, -50%);
-moz-transform: translate(-50%, -50%);
-ms-transform: translate(-50%, -50%);
-o-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
left: 50%;
top: 50%;
text-align: center;
}
Here is the JavaScript:
function popupOpenClose(popup) {
/* Add div inside popup for layout if one doesn't exist */
if ($(".wrapper").length == 0){
$(popup).wrapInner("<div class='wrapper'></div>");
}
/* Open popup */
$(popup).show();
/* Close popup if user clicks on background */
$(popup).click(function(e) {
if ( e.target == this ) {
if ($(popup).is(':visible')) {
$(popup).hide();
}
}
});
/* Close popup and remove errors if user clicks on cancel or close buttons */
$(popup).find("button[name=close]").on("click", function() {
if ($(".formElementError").is(':visible')) {
$(".formElementError").remove();
}
$(popup).hide();
});
}
$(document).ready(function () {
$("[data-js=open]").on("click", function() {
popupOpenClose($(".popup"));
});
});

Try this code, I have added a simple form. You can just change the css of the popup or the form as you need.
function toggleOn(){
$('body, #menu, #navbar, #content').toggleClass('on');
}
$(document).ready(function (){
$('#menu').click(function(){ toggleOn(); });
$('#content').click(function(){
if ($('#navbar').hasClass('on')) toggleOn();
});
});
//this is for the pop up
function popupOpenClose(popup) {
/* Add div inside popup for layout if one doesn't exist */
if ($(".wrapper").length == 0){
$(popup).wrapInner("<div class='wrapper'></div>");
}
/* Open popup */
$(popup).show();
/* Close popup if user clicks on background */
$(popup).click(function(e) {
if ( e.target == this ) {
if ($(popup).is(':visible')) {
$(popup).hide();
}
}
});
/* Close popup and remove errors if user clicks on cancel or close buttons */
$(popup).find("button[name=close]").on("click", function() {
if ($(".formElementError").is(':visible')) {
$(".formElementError").remove();
}
$(popup).hide();
});
}
$(document).ready(function () {
$("[data-js=open]").on("click", function() {
popupOpenClose($(".popup"));
});
});
//search bar
$(document).on('ready', function(){
var $wrap = $('[js-ui-search]');
var $close = $('[js-ui-close]');
var $input = $('[js-ui-text]');
$close.on('click', function(){
$wrap.toggleClass('open');
});
$input.on('transitionend webkitTransitionEnd oTransitionEnd', function(){
console.log('triggered end animation');
if ($wrap.hasClass('open')) {
$input.focus();
} else {
return;
}
});
});

You will need to format your
<div class="popup">
<h2>Subscribe to the Newletter:</h2><br>
<center><button name="close">Close Pop-up</button></center>
</div>
But you did not mention how do you want your popup to be displayed, i.e, center ? or anything other information. This works for me and looks good enough.
