Bootstrap 5: Navbar to the most right [duplicate]

How do I align a navbar item to right?
I want to have the login and register to the right.
But everything I try does not seem to work.
This is what I have tried so far:
<div> around the <ul> with the atribute: style="float: right"
<div> around the <ul> with the atribute: style="text-align: right"
tried those two things on the <li> tags
tried all those things again with !important added to the end
changed nav-item to nav-right in the <li>
added a pull-sm-right class to the <li>
added a align-content-end class to the <li>
This is my code:
<div id="app" class="container">
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">Navbar</a>
<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">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricingg</a>
</li>
</ul>
<ul class="navbar-nav " >
<li class="nav-item">
<a class="nav-link" href="{{ url('/login') }}">Login</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{{ url('/register') }}">Register</a>
</li>
</ul>
</nav>
#yield('content')
</div>

Bootstrap 5 (update 2021)
In Bootstrap 5 (see this question), ml-auto has been replaced with ms-auto to represent start instead of left. Since the Navbar is still based on flexbox, auto margins OR flexbox utility classes are still used to align Navbar content.
For example, use me-auto...
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand" href="#">Brand</a>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarContent">
<ul class="navbar-nav me-auto mb-2 mb-lg-0">
<li class="nav-item">
<a class="nav-link active" href="#">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false"> Menu </a>
<ul class="dropdown-menu dropdown-menu-end" aria-labelledby="navbarDropdown">
<li><a class="dropdown-item" href="#">Action</a></li>
<li><a class="dropdown-item" href="#">Another action</a></li>
</ul>
</li>
</ul>
</div>
</div>
</nav>
Bootstrap 5 right align Navbar content
Bootstrap 4 (original answer)
Bootstrap has many different ways to align navbar items. float-right won't work because the navbar is now flexbox.
You can use mr-auto for auto right margin on the 1st (left) navbar-nav.
Alternatively, ml-auto could be used on the 2nd (right) navbar-nav , or if you just have a single navbar-nav.
<nav class="navbar navbar-expand-md navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="#">Login</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Register</a>
</li>
</ul>
</div>
</nav>
https://codeply.com/go/P0G393rzfm
There are also flexbox utils. For example use justify-content-end on the collapse menu:
<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
<div class="container-fluid">
<a class="navbar-brand" href="#">Brand</a>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse justify-content-end" id="navbarNav">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link active" aria-current="page" href="#">Contact</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Download</a>
</li>
</ul>
</div>
</div>
</nav>
Or when you have 2 navbar-navs, use justify-content-between in navbar-collapse would work to even the space between the navbar-navs:
<div class="navbar-collapse collapse justify-content-between">
<ul class="navbar-nav mr-auto">
..
</ul>
<ul class="navbar-nav">
..
</ul>
</div>
Update for Bootstrap 4.0 and newer
As of Bootstrap 4 beta, ml-auto will still work to push items to the right. Just be aware the the navbar-toggleable- classes have changed to navbar-expand-*
Updated navbar right for Bootstrap 4
Another frequent Bootstrap 4 Navbar right alignment scenario includes a button on the right that remains outside the mobile collapse nav so that it is always shown at all widths.
Right align button that is always visible
Related: Bootstrap NavBar with left, center or right aligned items

In my case, I wanted just one set of navigation buttons / options and found that this will work:
<div class="collapse navbar-collapse justify-content-end" id="navbarCollapse">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="#">Sign Out</a>
</li>
</ul>
</div>
So, you will add justify-content-end to the div and omit mr-auto on the list.
Here is a working example.

For those who is still struggling with this issue in BS4 simply try below code -
<ul class="navbar-nav ml-auto">

On Bootstrap 4
If you want to align brand to your left and all the navbar-items to right, change the default mr-auto to ml-auto
<ul class="navbar-nav ml-auto">

On Bootsrap 4.0.0-beta.2, none of the answers listed here worked for me. Finally, the Bootstrap site gave me the solution, not via its doc but via its page source code...
Getbootstrap.com align their right navbar-nav to the right with the help of the following class: ml-md-auto.

Use this code to move items to the right.
<div class="collapse navbar-collapse justify-content-end">

Use ml-auto instead of mr-auto after applying nav justify-content-end to the ul

Just add mr-auto class at ul:
<ul class="nav navbar-nav mr-auto">
If you have menu list in both side you can do something like this:
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
<ul class="navbar-nav ml-auto">
<li class="nav-item active">
<a class="nav-link" href="#">left 1</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">left 2</a>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">left disable</a>
</li>
</ul>

If you want Home, Features and Pricing on left immediately after your nav-brand, and then login and register on right then wrap the two lists in <div> and use .justify-content-between:
<div class="collapse navbar-collapse justify-content-between">
<ul>....</ul>
<ul>...</ul>
</div>

In bootstrap v4.3 just add ml-auto in <ul class="navbar-nav">
Ex:<ul class="navbar-nav ml-auto">

use the flex-row-reverse class
<nav class="navbar navbar-toggleable-md navbar-light">
<div class="container">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false"
aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">
<i class="fa fa-hospital-o fa-2x" aria-hidden="true"></i>
</a>
<div class="collapse navbar-collapse flex-row-reverse" id="navbarNavAltMarkup">
<ul class="navbar-nav">
<li><a class="nav-item nav-link active" href="#" style="background-color:#666">Home <span class="sr-only">(current)</span></a</li>
<li><a class="nav-item nav-link" href="#">Doctors</a></li>
<li><a class="nav-item nav-link" href="#">Specialists</a></li>
<li><a class="nav-item nav-link" href="#">About</a></li>
</ul>
</div>
</div>
</nav>

It's little change in boostrap 4.
To align navbar to right side, you've to make only two changes.
they are:
in navbar-nav class add w-100 as navbar-nav w-100 to make width as 100
in nav-item dropdown class add ml-auto as nav-item dropdown ml-auto to make margin left as auto.
If you didn't understand, please refer the image that i've attached to this.

</ul>
</div>
</nav>

For bootstrap 4.3.1, I was using nav-pills and nothing worked for me except this:
<ul class="nav nav-pills justify-content-end ml-auto">
<li ....</li>
</ul>

In my case Bootstrap v5, I wanted just one set of navigation options to the right side:
just add "ms-auto" in ul.
And it helped me.
<div class="collapse navbar-collapse" id="navbarCollapse">
<ul class="navbar-nav ms-auto mb-2 mb-md-0">
<li class="nav-item">
<a class="nav-link " aria-current="page" href="index.php">Home</a>
</li>
<li class="nav-item">
<a class="nav-link " href="services.php" tabindex="-1" aria-disabled="true">Services</a>
</li>
<li class="nav-item">
<a class="nav-link" href="aboutus.php">About Us</a>
</li>
<li class="nav-item">
<a class="nav-link" href="Portfolio.php">Portfolio</a>
</li>
</ul>
</div>

The above answers surprisingly didn't work for me so here is my approach. To align the login and register navigation bar items to the right you can make use of either of these two ways:
pull-right:
Modify the unordered list tag for login and register as
<ul class="navbar-nav pull-right">
navbar-right:
Modify the unordered list tag for login and register as
<ul class="navbar-nav navbar-right">

I am running Angular 4 (v.4.0.0) and ng-bootstrap (Bootstrap 4). This code won't all be relevant but hoping people can pick and choose what works. It took me sometime to find a solution to get my items to justify right, collapse properly and to implement a dropdown off my google (using OAuth) profile picture.
<div id="header" class="header">
<nav class="navbar navbar-toggleable-sm navbar-inverse bg-faded fixed-top">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarSupportedContent"
aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">
<img alt='Brand' src='../assets/images/logo-white.png' class='navbar-logo-img d-inline-block align-top '>
<span class="navbar-logo-text">Oncoscape</span>
</a>
<div class="collapse navbar-collapse justify-content-end" id="navbarSupportedContent">
<ul class="navbar-nav float-left">
<a class="navbar-items nav-item nav-link active " *ngIf='authenticated' (click)='goDashboard()'>
<span class="fa fa-dashboard"></span>Dashboard
</a>
<a class="nav-item nav-link navbar-items active" href="http://resources.sttrcancer.org/oncoscape-contact">
<span class="fa fa-comments"></span>Feedback
</a>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
<img *ngIf='user && authenticated' class="navbar-pic" src={{user.thumbnail}} alt="Smiley face">
</a>
<div *ngIf='user && authenticated' class="dropdown-menu " aria-labelledby="navbarDropdownMenuLink">
<a class="dropdown-item" (click)="toProfile()">Account</a>
<div class="dropdown-item">
<app-login></app-login>
</div>
</div>
</li>
</ul>
</div>
</nav>
</div>
<router-outlet></router-outlet>

For Bootstrap 4 beta, sample navbar with elements aligned to the right side is:
<div id="app" class="container">
<nav class="navbar navbar-expand-md navbar-light bg-faded">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">Navbar</a>
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricingg</a>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="{{ url('/login') }}">Login</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{{ url('/register') }}">Register</a>
</li>
</ul>
</nav>
</div>

Using the bootstrap flex box helps
us to control the placement and alignment of your navigation element.
for the problem above adding mr-auto is a better solution to it .
<div id="app" class="container">
<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">Navbar</a>
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricingg</a>
</li>
</ul>
<ul class="navbar-nav " >
<li class="nav-item">
<a class="nav-link" href="{{ url('/login') }}">Login</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{{ url('/register') }}">Register</a>
</li>
</ul>
</nav>
#yield('content')
</div>
other placement may include
fixed- top
fixed bottom
sticky-top

The working example for BS v4.0.0-beta.2:
<body>
<nav class="navbar navbar-expand-md navbar-dark bg-dark">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavDropdown">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricingg</a>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="#">Login</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Register</a>
</li>
</ul>
</div>
</nav>
<div class="container-fluid">
container content
</div>
<!-- Optional JavaScript -->
<!-- jQuery first, then Popper.js, then Bootstrap JS -->
<script src="node_modules/jquery/dist/jquery.slim.min.js"></script>
<script src="node_modules/popper.js/dist/umd/popper.min.js"></script>
<script src="node_modules/bootstrap/dist/js/bootstrap.min.js"></script>
</body>

If all above fails, I added 100% width to the navbar class in CSS. Until then mr auto wasn't working for me on this project using 4.1.

but the nav item you want to align to right in alone
put it outside the of main nav but in the same , like that:
<ul class="navbar-nav justify-content-end ms-auto">
<li class="nav-item">
<a class="nav-link" href="#" aria-expanded="false">Contact support</a>
</li>
<li class="nav-item ">
<a class="nav-link" href="#" aria-expanded="false">Log in</a>
</li>
</ul>
use justify-content-end ms-auto

Find the 69 line in the verndor-prefixes.less and write it following:
.panel {
margin-bottom: 20px;
height: 100px;
background-color: #fff;
border: 1px solid transparent;
border-radius: 4px;
-webkit-box-shadow: 0 1px 1px rgba(0,0,0,.05);
box-shadow: 0 1px 1px rgba(0,0,0,.05);
}

Just copied this from one of the getbootstrap pages for the released version 4 which worked much better than the above
<div class="d-none d-xl-block col-xl-2 bd-toc float-md-right">
<ul class="section-nav">
<li class="toc-entry toc-h2">Overview</li>
<li class="toc-entry toc-h2">Classes</li>
<li class="toc-entry toc-h2">Mixins</li>
<li class="toc-entry toc-h2">Responsive</li>
</ul>
</div>

I'm new to stack overflow and new to front end development. This is what worked for me. So I did not want list items to be displayed.
.hidden {
display:none;
}
#loginButton{
margin-right:2px;
}
<nav class="navbar navbar-toggleable-md navbar-light bg-faded fixed-top">
<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<a class="navbar-brand" href="#">NavBar</a>
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<ul class="navbar-nav mr-auto">
<li class="nav-item active hidden">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item hidden">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item hidden">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
<form class="form-inline my-2 my-lg-0">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit" id="loginButton">Log In</button>
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Register</button>
</form>

Why I can't move img and alink text and my navbar don't work?

[enter image description here][1]I tried to much to move the image and link button and tried to make the navbar works on mobile but not very good
I used this code to try to move my image and the link:
<td width="500px"><img src="img/amd.jpeg" style=" top: 10%;" align="centre">
<td width="500px"><img src="img/amd.jpeg" >
and this the bootstrap navbar that don't work:
<nav class="navbar navbar-expand-md bg-dark navbar-dark">
<!-- Brand -->
<a class="navbar-brand" href="#">Navbar</a>
<!-- Toggler/collapsibe Button -->
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#collapsibleNavbar">
<span class="navbar-toggler-icon"></span>
</button>
<!-- Navbar links -->
<div class="collapse navbar-collapse" id="collapsibleNavbar">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
</ul>
</div>
</nav>
and I tried to resize the link text by this code but doesn't work too :
<a href="CPU.html" style="
text-decoration: none;
color: black; " ><b size="50">CPU</b></a>
This was a pity
and I tried to make it as I made it in Nicepage

How to change navigation scroll down?

When scrolling down after a div the nav-bar gets a new background-color (the nav-bar should be fixed at the top, I use navbar-fixed-top in Bootstrap).
I've tried some tutorials but I didn't succeed.
I have two menus #scroll-menu and #main-menu. I wnat to show #main-menu when open a browser. and when I scroll down the #main-menu do not show. the #scroll-menu be show.

My nav toggler icon is not displayed but while clicked on that region it works fine. What can I do to resolve this

After setting custom background for the nav-bar in bootstrap 4, I tried to put nav-toggler-icon for small screens. the nav-bar hamburger icon is not displayed but when I click the region it works fine. What can I do for it.
The html code is:
<nav id=header-nav class="navbar navbar-expand-md navbar-custom ">
<a href="index.html" class="navbar-brand">
<h1 class="tagline">Subha</h1>
</a>
<button class="navbar-toggler" data-toggle="collapse" data-target="#hamburger">
<span class=" navbar-dark navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="hamburger">
<ul class="navbar-nav ml-auto">
<li class="nav-item">
Cart</li>
<li class="nav-item">
Login</li>
</ul>
</div>
</nav>
the css code for nav bar is:
.navbar-custom
{
background-color: rgb(144,12,25);
border-radius: 0;
border: 0;
}

Try to change
data-target="#hamburger"
to
data-target="#navbarResponsive"
I hope this helps you! Otherwise take my own navbar template:
<nav class="navbar navbar-expand-md navbar-light bg-light sticky-top">
<div class="container-fluid">
<img src="img/logo.png" alt="Logo" />
<!-- dropdown btn -->
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive">
<span class="navbar-toggler-icon"></span>
</button>
<!-- nav-links -->
<div class="collapse navbar-collapse" id="navbarResponsive">
<ul class="navbar-nav ml-auto">
<li class="nav-item active">
home
</li>
<li class="nav-item">
about
</li>
<li class="nav-item">
services
</li>
<li class="nav-item">
team
</li>
<li class="nav-item">
connect
</li>
</ul>
</div>
</div>
</nav>

Your <nav> is missing the color scheme color class, Which is what bootstrap uses to add the icon to the button.
The problem is you misplaced it, it should go on the <nav> not the <span>, It's only visible when you click it because the an outline as applied.
Demo
body {
zoom: 2;
}
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css">
<div class="navbar-light bg-primary">
<span class="navbar-toggler-icon"></span>
</div>
<br>
<div class="navbar-dark bg-primary">
<span class="navbar-toggler-icon"></span>
</div>
Solution
.navbar-custom {
background-color: rgb(144, 12, 25);
border-radius: 0;
border: 0;
}
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css">
<nav id=header-nav class="navbar navbar-expand-md navbar-dark navbar-custom ">
<a href="index.html" class="navbar-brand">
<h1 class="tagline">Subha</h1>
</a>
<button class="navbar-toggler" data-toggle="collapse" data-target="#hamburger">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="hamburger">

How to right align text in Navigation Bar - HTML

<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavAltMarkup">
<div class="navbar-nav">
<a class="nav-item nav-link active" href="#">Home <span class="sr-only">(current)</span></a>
<a class="nav-item nav-link" href="#">Features</a>
<a class="nav-item nav-link" href="#">Pricing</a>
<a class="nav-item nav-link disabled" href="#">Disabled</a>
</div>
</div>
</nav>
So I just recently started practicing HTML and CSS on my own time. I just started building a website using bootstrap and I'm having trouble with this navigation bar: navbar You can find it on this webstie: https://getbootstrap.com/docs/4.0/components/navbar/
and scroll down to "Nav" (i dont know how to include HTML code here)
What I want to do is have the items "Home" "Features" "Pricing" and "Disabled" "Search" (A search bar that I will implement) floating to the right. Eventually I will have something like:
NavBar-----------------------------------------------------------------Home Features Pricing Disabled #Search
But I can't seem to do it. I've tried to use span tags, ul tags, I've tried to remove some div elements but nothing is working. Any help?
Also I have a question. If I put:
"Navbar"
inside a div, then it is still inline with the rest of the nav elements (Home, Pricing etc...) which are in a different div. How is that possible?
Aren't divs block elements?

Learn and use FlexBox
It is a very powerful css layout library that is supported by most browsers.
Check out an example here for the Nav Bar. There are many ways you can right align. One way is to have an empty element just to the left of the nav elements that takes up remaining space which pushes the elements all the way to the right.
To achieve this for the Bootstrap example
All I did was add
<div style="flex-grow: 1;"></div>
Right below
<div class="collapse navbar-collapse" id="navbarSupportedContent">
And right above
<ul class="navbar-nav mr-auto">

If you're only looking to use Bootstrap features, you can achieve this by wrapping your links with this:
<ul class="nav navbar-nav navbar-right">
<links>
</ul>
Without using bootstrap:
.align-left { float: left }
.align-right { float: right }
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="align-left">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
</div>
<div class="collapse navbar-collapse align-right" id="navbarNavAltMarkup">
<div class="navbar-nav">
<a class="nav-item nav-link active" href="#">Home <span class="sr-only">(current)</span></a>
<a class="nav-item nav-link" href="#">Features</a>
<a class="nav-item nav-link" href="#">Pricing</a>
<a class="nav-item nav-link disabled" href="#">Disabled</a>
</div>
</div>
<div style="clear: both;"></div>
</nav>

You can use the class mr-auto to fix the elements to the right.
Your code will become :
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavAltMarkup">
<div class="navbar-nav mr-auto">
<a class="nav-item nav-link active" href="#">Home <span class="sr-only">(current)</span></a>
<a class="nav-item nav-link" href="#">Features</a>
<a class="nav-item nav-link" href="#">Pricing</a>
<a class="nav-item nav-link disabled" href="#">Disabled</a>
</div>
</div>
</nav>
