I am using jQuery to add active to my menu. It works on the index page, but I can't get it to work on the other pages right now. I've tried changing around the web address to fit the exact location.pathname but that doesn't seem to work, and I tried dropping the \ prior to it as well. Any help would be appreciated.
my markup:
<nav class="sticky-top navbar navbar-expand-lg navbar-light bg-myColor">
<a class="navbar-brand" href="#">
<img src="image/VC-Logo.png" alt="Visionary Creatives logo" height="150px;" />
</a>
<button class="navbar-toggler navbar-brand" type="button" data-toggle="collapse" data-target="#navToggle" aria-controls="navToggle" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navToggle">
<ul class="navbar-nav mr-auto mt-2 mt-lg-0">
</ul>
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="/">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="/coming-soon.php">Web Design</a>

</li>
<li class="nav-item">
<a class="nav-link" href="/coming-soon.php">Contact Us</a>
</li>
</ul>
</div>
</nav>
and my jQuery:
$(document).ready(function() {
$('.navbar-nav .nav-item a[href="' + this.location.pathname +
'"]').parent().addClass('active');
});
and my website if this helps as well:
http://www.visionary-creatives.com

So I'm creating a simple website with Laravela and Vue.js, and website to be responsive I added bootstrap 4. Everything works fine, navbar collapses when it should, and toggle button shows up and when I click it, it displays everything. But when I click the toggle button to hide navbar it just flickers and doesn't do anything.
<!--Navigation bar-->
<nav class="navbar navbar-expand-sm navbar-light bg-light">
<a class="navbar-brand" href="#">website<span id = "EditorColorist">editor colorist</span></a>
<button class="navbar-toggler" data-toggle="collapse" data-target = "#collapsibleNavId">
<span class = "navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="collapsibleNavId">
<ul class="navbar-nav ml-auto">
<li class="nav-item">
<a class="nav-link" href="/">HOME</a>

</li>
<li class="nav-item">
<a class="nav-link" href="/contact">CONTACT</a>
</li>
</ul>
</div>
</nav>
<!--Navigation bar-->
And yes I added JS, Jquery before CSS.
I created a simple snippet for this to test and it the toggler on there works just fine for me. Feel free to try for yourself.

You could try checking your css to make sure that you don't have any classes that clash with those that bootstrap uses. I've seen that happen and cause issues with the way the navbar works.
I have a bootstrap navbar which expands at md breakpoint and is made of 2 submenus the collapsing of which is controlled by two buttons with navbar-toggler class.
I want to have my navbar to expand at md but one of my submenu (account) stay always toggled (button that trigger the content show under the navbar).
I'm not experimented with js but I guess it's possible to do it via a script. I've also seen in the source code that when the navbar expand the navbar-toggler get display:none which is a problem.
Here is my navbar and a js script to control the 2 submenus collapse:
$('#links').on('show.bs.collapse', function() {
$('#account').collapse("hide");
})
$('#account').on('show.bs.collapse', function() {
$('#links').collapse("hide");
})

This part of your javascript $('#account').collapse() doesn't get executed because the account div is not yet loaded. Wait for it to load then execute the line, like this:
window.onload = function(){
$('#account').collapse();
}
it should do the trick.
$('#links').on('show.bs.collapse', function() {
$('#account').collapse("hide");
})
$('#account').on('show.bs.collapse', function() {
$('#links').collapse("hide");
})
$('#account').collapse()

So I spent a few hours trying to solve this myself, with the help of other people's posts but had no luck. Allow me to explain my issues first.
My website, www.discoverbugs.org, has a bootstrap navigation menu. It looks fine on the desktop, but on mobile, the drop-down menu disappears when you click on it. What's causing it and how can I fix it?
The second issue is the header image. On mobile, it expands across the entire width of the phone. I'm having this issue with a lot of images on the site. I tried adding max and min widths and it just won't work for me. Can someone please help me edit this? It looks ridiculous.
CSS:
#media screen and (max-width: 420px) { header {
padding: 65px 0 0px; } }
Index.php
<header class="bg-primary text-white">
<div class="container text-center">
<img src="img/header-v6.jpg">
</div>
</header>
Header.php (Navigation menu)

Javascript coding I have:
<script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script>
The reason is simple: Bootstrap 3 JavaScript is not designed to work with Bootstrap 4.
In other words, for Bootstrap 4 css you also need Bootstrap 4 JavaScript (as well as jQuery 3.2.1 and popper.js).
To fix the header image issue add the img-fluid class to the image like so:
<img class="img-fluid" src="img/header-v6.jpg">
This will make the image responsive.
To fix the first issue, use the css and JavaScript files from the following template (and load them in that order):
<!doctype html>
<html lang="en">
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

I would like to have a sticky header and menu #fixedheader and a sticky sidebar #stickySocialIcons. I already tried position:fixed but the problem is that the whole website gets effected...
And regarding the sticky sidebar my problem is that if I use position:fixed the sidebar doesn't stop at the footer with the background and that it doesn't starts to stick to the screen when the screen touches the sidebar. It is always at the same position...
Does anybody has an idea, how I can fix that?
Here the website I am talking about: https://classymagazin.de/home/
Kind regards
This is a some idea for you , think a minuet you can do it

Try this css and JQuery for sticky header
#fixedheader {
position: fixed;
width: 100%;
z-index: 9999;
background: #fff;
}
JQuery
$(document).ready(function () {
var sticky = $('#fixedheader');
var height = sticky.height();
$(document.body).css('margin-top', height + "px");
});
