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As of Bootstrap 5 beta, left and right have been replaced by start and end for RTL support.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>

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:

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-giJF6kkoqNQ00vy+HMDP7azOuL0xtbfIcaT9wjKHr8RbDVddVHyTfAAsrekwKmP1" crossorigin="anonymous">



<nav class="navbar navbar-dark bg-dark">
  <div class="container-fluid">
    <a class="navbar-brand">Navbar</a>
    <form class="d-flex">
      <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
      <button class="btn btn-outline-success" type="submit">Search</button>
    </form>

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 🙂

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">

This worked for me:

<div class="d-flex flex-row-reverse">

I have used d-flex for right side alignment

If the “mb-2” and “mb-lg-0” class is not necessary, simply use the following code, and it should work. Otherwise, you can try adding the “mb-2 mb-lg-0” class to the code.
