trying to work out navbars right now, but my code doesn't seem to work with them.
The collapse icon is staying next to the navbar-brand and then the navbar-links are sitting next to it.

you have to add navbar-toggler class instead of navbar-toggle to the button see the code:
<nav id="mainNavbar "class="navbar navbar-dark bg-dark navbar-expand-md">
<a class="navbar-brand" href="#">TEST</a>
<button class="navbar-toggler" data-toggle="collapse" data-target="#nav-links">
<span class="navbar-toggler-icon" id="navbar-icon"></span>
</button>
<div class="collapse navbar-collapse" id="nav-links">
<ul class="navbar-nav">
<li class="nav-item">
HOME
</li>
<li class="nav-item">
ABOUT
</li>
<li class="nav-item">
TICKETS
</li>
</ul>
</div>
</nav>
Problem is with your button change your class navbar-toggle to navbar-toggler
<button class="navbar-toggler" data-toggle="collapse" data-target="#nav-links">
<span class="navbar-toggler-icon" id="navbar-icon"></span>
</button>

I am having trouble right aligning elements in my navbar with bootstrap. For some reason, the elements seemed fixed and even using an external css file did not help. The look im aiming for is keeping the logo and name or "brand" on the left, with the rest of the 'items' right-aligned. For some reason, the 'ml-auto' class of bootstrap is not working either.
HTML:
.navbar-nav {
margin-left: auto;
}

Could someone share what might be the issue? Any help is appreciated.
Small example. Only bootstrap classes without any additional CSS. In your example, the first div destroys the nav because it's not 100% wide. Btw here's another example. In your navbar the whole mobile view is broken. The example below is completely working with desktop and mobile devices.
Hopefully it will work :)

As seen here, the Navbar overlaps the text in the body. How can I fix this? This is what it looks like on desktop.
Here is my code for the Navbar:
<nav class="navbar navbar-expand-sm bg-dark navbar-dark fixed-top">
<!-- Logo -->
<a class="navbar-brand" href="index.html">
<img src="black_hole.jpg" alt="logo" style="width: 40px;height: 40px;">
</a>
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="portfolio.html">Portfolio</a>
</li>
<li class="nav-item">
<a class="nav-link" href="beermoney.html">BeerMoney Routine</a>
</li>
<li class="nav-item">
<a class="nav-link" href="mailto:(my_email_here)#gmail.com">Contact Me</a>
</li>
</ul>
</nav>
Then the rest of the code is the body text.
Any help is appreciated. I'm going on vacation, so I will try to respond to your comments the best I can, but no guarantees.
(All Code here)
You can remove the .fixed-top class from <nav> element to show the content all the time. So you can also remove the margin-top: 90px; (or adjust the value) to remove / adjust the gap between navigation and content.

In case you want to use the fixed navigation, you have to add support for the responsive navgation so you can toggle on mobile.

I am trying to use a nav bar with links and a collapsible menu for small screens. However, I am having two issues:
On normal size screens, the links do not show up
On mobile, when clicking the menu open button, the menu opens but collapses immediately.
Here is a link to my code on jsfiddle. Thanks

I created a Navbar with Bootstrap 4. The "Logout" button on the left side in the Navbar appears much to wide, when the navbar is collapsed.
How can I fix the big "Logout" button if the navbar is collapsed??
