Bootstrap button in nav horizontal menu causes text misalignment - html

I have some code that was substantially produced by ASP.NET Core scaffolding. I'm a CSS novice. The problem is that in this menu there is a button that causes the option to its left to be slightly higher than the other options. The button is Logout and the option to its left is Profile. Through trial and error I have narrowed the cause to the btn class on Logout.
Why is this happening and what is the fix?
Here's a web page that replicates the problem.

There's default 1PX border CSS for the btn class on Bootstrap-4 which causes the issue as it is not applied on the 'Profile' #manage element.
Why does the border have the effect?
In CSS, elements have their own border property. The border will be invisible if its style is not defined. This is because the style defaults to none. In our case, border is defined with 1px which consume space around the element. If border to set like border: 0 or border: none, this will not consume any space.
Why isn't Home affected? It doesn't have the btn style.
'Home' are wrapped under container <ul> which having bootstrap flex-grow-1 class and this flex-grow-1 class applied flex-grow: 1 css to the element.
And how does CSS `flex-grow' work?
Flex-grow tells our element whether or not it can take up additional space. When we set a flex-grow value of 1 or larger, we are telling our element to grow to take up the available space. An element with a flex-grow value set to 0 will not grow to take up available space.
This flex-grow doc also helps you.
Snippet:
#manage {
border: 1px solid transparent;
}

Here, short code snippet where 3rd and 4th menu doesn't have btn class but 4th menu have flex-grow css to their parent container which lead 4th menu to occupy space and looks similar to the 2nd menu :
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
<header>
<nav class="navbar navbar-expand-sm navbar-toggleable-sm navbar-light bg-white border-bottom box-shadow mb-3">
<div class="container">
<div class="navbar-collapse collapse d-sm-inline-flex justify-content-between">
<ul class="navbar-nav">
<li class="nav-item">
<a id="manage" class="nav-link text-dark" asp-area="Identity" asp-page="/Account/Manage/Index" title="Manage">Menu</a>
</li>
<li class="nav-item">
<a id="logout" class="nav-link btn btn-link text-dark">Menu with border (btn)</a>
</li>
<li class="nav-item">
<a class="nav-link text-dark" asp-area="" asp-controller="Home" asp-action="Index">Menu</a>
</li>
</ul>
<ul class="navbar-nav flex-grow-1">
<li class="nav-item">
<a class="nav-link text-dark" asp-area="" asp-controller="Home" asp-action="Index">Menu with <i>flex-grow</i></a>
</li>
</ul>
</div>
</div>
</nav>
</header>
Now here, 3rd and 4th menus doesn't have btn class and also 4th menu doesn't have flex-grow-1 bootstrap css class to their parent <ul> element. In this case, 4th menu doesn't occupy additional space and looks similar to the 1st and 3rd menu irrespective of wrapping into another <ul></ul> element :
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">

<header>
<nav class="navbar navbar-expand-sm navbar-toggleable-sm navbar-light bg-white border-bottom box-shadow mb-3">
<div class="container">
<div class="navbar-collapse collapse d-sm-inline-flex justify-content-between">
<ul class="navbar-nav">
<li class="nav-item">
<a id="manage" class="nav-link text-dark" asp-area="Identity" asp-page="/Account/Manage/Index" title="Manage">Normal Menu</a>
</li>
<li class="nav-item">
<a id="logout" class="nav-link btn btn-link text-dark">Menu with "btn"</a>
</li>
<li class="nav-item">
<a class="nav-link text-dark" asp-area="" asp-controller="Home" asp-action="Index">Normal menu</a>
</li>
</ul>
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link text-dark" asp-area="" asp-controller="Home" asp-action="Index">Normal menu</i></a>
</li>
</ul>
</div>
</div>
</nav>
</header>


Home is not affected because it is in another unordered HTML list, if you remove
</ul><ul class="navbar-nav flex-grow-1"> between the second and third nav-item then you will see Home not aligned with Logout as you can see in the following snippet:
#manage {
border: 1px solid transparent;
}

To solve the issue you need all the nav-item elements to be in the same unordered HTML list and then if the classes have borders like in this case where the btn class has, you should make all the nav-item elements have the same classes. As #cursorrux said Logouthas a transparent border and all the others don't.

Bootstrap Navbar toggle icon button not showing nav items on click?

I have been using bootstrap in projects very smoothly, but then in one angular project, its navbar toggler icon button is appearing but not showing the nav items on clicking the button.
<div>
<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
<div class="container">
<a class="navbar-brand" href="#">Admin Header</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" id="navbarResponsive">
<ul class="navbar-nav ml-auto">
<li class="nav-item" routerLinkActive="active">
<a class="nav-link" routerLink="./home">Home
<span class="sr-only">(current)</span>
</a>
</li>
<li class="nav-item" routerLinkActive="active">
<a class="nav-link" routerLink="./about">About</a>
</li>
<li class="nav-item" routerLinkActive="active">
<a class="nav-link" routerLink="./services">Services</a>
</li>
<li class="nav-item" routerLinkActive="active">

<a class="nav-link text-white" (click)="logOut()" >logout</a>
</li>
</ul>
</div>
</div>
</nav>
</div>
This is the Navbar result:
On decreasing the width of the browser we have results something like this:
below is the code of index.html:
But on clicking on this button I am not able to see any nav items.

Works perfectly fine, you must be missing some script files.

Navbar when clicked is not redirecting to another page bootstrap 5

The issue is that when I click the navbar item it's not redirecting to the page and not giving any feedback. But when I delete the bootstrap.bundle.min.js it's working as it should be, but the expand button for the navbar when it's collapsed is not working.

The problem is the data-bs-toggle="collapse" data-bs-target=".navbar-collapse.show" on the navbar-collapse div. Remove it and the navigation will work fine.

Demo
Also, jQuery is not required for Bootstrap 5

Move navbar object [duplicate]

How do you align Bootstrap 5 navbar items to the right? In Bootstrap 3 it's navbar-right. In Bootstrap 4 it's ml-auto. But not work for Bootstrap 5.

Bootstrap 5 (update 2021)
As of Bootstrap 5 beta, left and right have been replaced by start and end for RTL support. Therefore the margin utilities changed for Bootstrap 5 beta:
ml-auto => ms-auto (start)
mr-auto => me-auto (end)
Also note, all uses of left and right have been replaced with start and end in Bootstrap 5...
ml-* => ms-*
pl-* => ps-*
mr-* => me-*
pr-* => pe-*
text-left => text-start
text-right=> text-end
float-left => float-start
float-right=> float-end
border-left => border-start
border-right=> border-end
rounded-left => rounded-start
rounded-right=> rounded-end
dropleft => dropstart
dropright=> dropend
dropdown-menu-left => dropdown-menu-start
dropdown-menu-right => dropdown-menu-end
carousel-item-left => carousel-item-start
carousel-item-right=> carousel-item-end
Bootstrap 5 alpha (original answer)
This question was asked for Bootstrap 5 alpha, and therefore ml-auto should still work.
How to align nav items to the right in Bootstrap 5?

I changed mr-auto to ms-auto and it worked for me, this is the best solution.
<ul class="navbar-nav ms-auto mb-2 mb-lg-0">

You need to use ms-auto instead of ml-auto in bootstrap 5.
Horizontal direction sensitive variables, utilities and mixins are renamed with more logical names — start and end in lieu of left and right in Bootstrap 5.
Renamed .left-* and .right-* to .start-* and .end-*.
Renamed .float-left and .float-right to .float-start and .float-end.
Renamed .border-left and .border-right to .border-start and
.border-end.
Renamed .rounded-left and .rounded-right to .rounded-start and
.rounded-end.
Renamed .ml-* and .mr-* to .ms-* and .me-*.
Renamed .pl-* and .pr-* to .ps-* and .pe-*.
Renamed .text-left and .text-right to .text-start and .text-end.
You can see more bootstrap 5 migration details here:
https://getbootstrap.com/docs/5.0/migration/#sass

The justify-content-end class makes the difference.
<div class="collapse navbar-collapse justify-content-end" id="navbarResponsive">

This question is already answered here
For more clarification, as per Bootstrap 5 documentation, some utilities are renamed. including left and right.
left ==> start
right ==> end
therefore
ml has changed to ms
mr has changed to me
so right now:
ml-auto ==> ms-auto
mr-auto ==> me-auto
you can see this here in bootstrap documentation
Therefore, if you want your navbar items to be aligned "right", you have to put:
<div class="collapse navbar-collapse" id="navbarScroll">
<ul class="navbar-nav ms-auto mb-2 mb-lg-0">
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
</ul>
</div>

This one worked fine for me,
check this out :
<ul class="navbar-nav ms-auto mb-2 mb-lg-0">

Replace mr-auto with ms-auto
This worked for me, hope it helps you :)

It is the same as Bootstrap 4 you should use ml-auto. Here is a snippet from. Navbar Bootstrap 5 offical
And here is the official home page for Bootstrap 5

Edit
The question was asked when bootstrap 5 was in alpha. But right now we have beta out and they did change the naming to be margin-start and margin-end
Renamed .ml-* and .mr-* to .ms-* and .me-*
Renamed .pl-* and .pr-* to.ps-* and .pe-*
So the answer should be like this:

I gave my <div class="collapse navbar-collapse" id="navLinks"> an #id. then in css, I used the id to #navLinks {justify-content:flex-end;}. Workred fine. Just run the code and do full page.
body {
background: #f5d9d5;
}
#navLinks {
justify-content: flex-end;
}
#home, #about, #portfolio, #testimonials {
margin: 2em 1em 0 1em;
font-size: large;
}
#brand_name {
font-size: 1.75em;
font-weight: 500;
padding-top: 4vh;
}
#bavbar-button {
align-items: flex-end;

As an alternative approach, you can try flex:
<nav class="navbar navbar-dark bg-dark d-flex justify-content-end">

"dependencies": {
"bootstrap": "^5.1.3",
"next": "12.1.4",
"node-sass": "^7.0.1",
"react": "18.0.0",
"react-bootstrap": "^2.2.3",
"react-dom": "18.0.0"
},
first option
<Navbar.Collapse id="basic-navbar-nav" className="justify-content-end">
<Nav>
<Link href="/" passHref>
<Nav.Link>Home</Nav.Link>
</Link>
</Nav>
</Navbar.Collapse>
className="justify-content-end"
or second option
<Navbar.Collapse id="basic-navbar-nav">
<Nav className="ms-auto">
<Link href="/" passHref>
<Nav.Link>Home</Nav.Link>
</Link>
</Nav>
</Navbar.Collapse>
className="ms-auto"

This worked for me:
<div class="d-flex flex-row-reverse">

I have used d-flex for right side alignment

Want to have Nav-Item be same height as Nav-Bar

I am using Bootstrap 4 and trying to make a nav-item have the same height as my navbar so that when I add background-color to it it looks like a stripe through the nav-bar.
Initially the item was centered and left space on top and below. I added negative margin to get it up against the top but the same didn't work when I tried to add "margin-bottom"
I then tried fixing the height of the navbar but when I did that and clicked on the toggle to bring down the navbar items they didn't show up because the fixed height prevented it from appearing.
<body>
<nav class="navbar navbar-dark bg-dark text-center">
<div class="container">
<div class="mr-auto order-0" class= "d-flex align-items-stretch">
<a class="navbar-brand ml-auto" style="background-color:red; line-height: 58px; margin-top:-9px; padding: 0 20px 0 20px;" class="nav-item active" href="#">Matthew Krebs</a>
</div>
<a class="navbar-brand text-center" href="#"></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" id="navbarResponsive">
<ul class="navbar-nav ml-auto mx-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home
</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>

A few things:
I changed the inline CSS to a separate class just for the red background
added the nav-link class so that you can see the behavior of the nav-item on the top and those which are revealed upon clicking the burger menu
the navbar class had a padding which we had to overwrite to take care of the stripe look
make sure that your CSS is loaded after bootstrap, so that you can override it without using !important
working snippet below:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js"></script>
<nav class="navbar navbar-dark bg-dark text-center">
<div class="container">
<div class="mr-auto order-0" class="d-flex align-items-stretch">
<a class="nav-item nav-link my-custom-style" href="#">Matthew Krebs</a>
</div>
<a class="navbar-brand text-center" href="#"></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" id="navbarResponsive">
<ul class="navbar-nav ml-auto mx-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home
</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
</ul>
</div>
</div>
</nav>
<style>
.navbar {
padding-top: 0;
padding-bottom: 0;
}
/* just to highlight our nav-item */
.my-custom-style {
background-color: red;
}
.nav-link {
border: 1px dotted yellow;
}
</style>

The desired effect can be achieved by simply removing the padding from the <nav> element. The easiest way to do this is to add the p-0 class to the <nav>. Bootstrap includes several margin and padding utility classes. Read about them here.
<nav class="navbar navbar-dark bg-dark text-center p-0">
<div class="container">
<div class="mr-auto order-0" class="d-flex align-items-stretch">
<a class="navbar-brand ml-auto"class="nav-item active" href="#">
Matthew Krebs
</a>

<button class="navbar-toggler" data-toggle="collapse" data-target="#navbarResponsive">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">

<li class="nav-item active">

Bootstrap mobile menu disappears after toggle

I have an Umbraco site that I'm integrating with Bootstrap. I've created a partial view with a navigation menu and everything seems to be working as intended with the exception of the navbar.
So when you click on the button it expands but immediately snaps back up. When you toggle it back, it almost 'pops into existence' and moves back up to close. Here is the entire output of the DOM
