I put the code into codepen and the page displays properly there. See for yourself:

I think this works fine. :)
Try this out...
If this doesn't work tell me what size screen you are viewing this on.

Red is the border color of the href.
Black is the image border.
The following code that i use:
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

Has somebody an explanation for this whats going wrong or is it just a bug in ios on this device?
I'm building a site in Bootstrap and my hamburger menu is not collapsing. Here is the HTML code:
<section>
<div class="container-fluid main-banner">
<div class="row">
<div class="col-12">

</div>
</div>
</section>
I would appreicate any feedback as I am pretty much stumped at this point. I've tried looking on other threads but haven't found anything yet.
You need to call id used in data-target="#navbarSupportedContent" for show hide navbar div please check below code
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<meta name="viewport" content="width=device-width, initial-scale=1">

Is is possible to create 2 different navbar's using Bootstrap 4.3.x like the image below?
With the first navbar (with Sample Brand) fixed to top, and the second navbar scrollable?
Not sure if there is a utility from Bootstrap I can use to handle this.
Im tried adding a 'margin-top: 56px' on the second navbar which will give a space allowance, but this only works with large screens, as the first navbar's height will change when the burger menu icon shows.
My current code is:
<nav class="navbar navbar-expand-lg navbar-dark fixed-top" >
<div class="container">
<a class="navbar-brand" href="#">
Sample Brand
</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse flex-column" id="navbarResponsive">
<ul class="navbar-nav ml-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Login
<span class="sr-only">(current)</span>
</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Register</a>
</li>
</ul>
</div>
</div>
</nav>
<nav class="navbar navbar-expand-lg navbar-dark p1-primary static-top" style="margin-top: 56px">
<div class="container">
<div class="collapse navbar-collapse" id="navbarResponsive">
<ul class="navbar-nav ">
<li class="nav-item active">
<a class="nav-link" href="#">Home
<span class="sr-only">(current)</span>
</a>
</li>
<li class="nav-item font-weight-lighter">
<a class="nav-link" href="#">FAQs</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Developer</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Contact Us</a>
</li>
</ul>
</div>
</div>
</nav>
This runs ok with large screens, but when I test it on small and medium screens, this happens:
Not really sure what margin-top value should I use as Bootstrap's navbar has no fixed height.
As much as possible, I do not want to do it with javascript as I think there a possible way in css (which I just dont know. Ikr haha!) and using javascript is an overkill. Hehe
You have your secondary navbar set to navbar-expand-lg so it changes to the collapsed navbar at the md breakpoint. If you want it to stay expanded, change the expand breakpoint. e.g. navbar-expand-md or navbar-expand-sm or for all viewport sizes navbar-expand
Below is an example with the secondary nav expanded in all viewports

This is very similar to Bootstrap 4 Multiple fixed-top navbars except the 2nd Navbar is static. The margin-top on the 2nd Navbar is fine.
However, "this runs ok with large screens, but when I test it on small and medium screens, this happens..."* is the problem, because the 2nd Navbar loses its height because it has no navbar-brand. The 2nd Navbar shouldn't be collapse at all and should be expanded...
<nav class="navbar navbar-expand-lg bg-dark navbar-dark fixed-top" >
<div class="container">
<a class="navbar-brand" href="#">
Sample Brand
</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target=".navbar-collapse" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">

I'm unable to open the hamburger menu while using bootstrap. Would somebody please tell me what the issue is with the code?
I've pulled the code directly from the bootstrap website. I've looked at others' questions regarding this problem, but the suggested solutions haven't helped.

Please explain this for me very simply, as I'm new to coding. I want to be able to open the hamburger menu on a mobile device.
data-target and the id were not the same.
You need the jquery and bootstrap.js for the dropdown to work.

for people looking for a solution in bootstrap 5, you should replace data-target with data-bs-target.
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#forum_navbar"
aria-controls="forum_navbar" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>

Sometimes people only import Bootstrap CSS CDN link. They need to be import JavaScript SDN link also for the Hamburger menu etc.
Something to note is the # in data-bs-target which references the id. I didn't notice this small element in the beginning and the hamburger menu wasn't working when clicked.
Having issues with the collapsing menu still. According to the way bootstrap is set up, when it collapses, it should go into a straight vertical nav instead of still stretching horizontal. It only seems to end up vertically correct when at the lowest screen size and even though only displays correctly on one of the menus. Thank you Gary for pointing out and helping fix the first issue with the buttons and ID's
first image is how it's supposed to look

Your target attribute for both the navbar is same. Just replace the target attribute and the button works for different nav bar. And the navbar seems to become vertical when the width of the browser is less.
