How to center nav-items in Bootstrap? [duplicate]

What if I want to center the nav-items (links) on the navbar according to the browser window size in Bootstrap 4. Take a look at the code:

<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
    <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="#">Navbar</a>
    <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>

Now I want to center the div "navbar-nav" according to browser width. One thing that I have tried is giving it mr-auto and ml-auto which does seem to center it but not exactly. What it actually does it centers it according to the width "browser window width - logo width" . I want it centered exactly in the middle of the screen.

I have tried changing position to absolute as well but again that kind of messes up layout in collapsed mode as well.

Solution 1:

Use the flexbox and margin utils responsively...

Bootstrap 4 alpha 6 http://codeply.com/go/YvzHvQQRAs (center brand & links)

<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
    <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>
    <div class="d-md-flex d-block flex-row mx-md-auto mx-0">
        <a class="navbar-brand" href="#">Navbar</a>
        <div class="collapse navbar-collapse mr-auto" 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>
</nav>

EDIT..

The answer is still basically the same. Use mx-auto to center.

<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
    <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="#">Navbar</a>
    <div class="collapse navbar-collapse" id="navbarNavAltMarkup">
        <div class="navbar-nav mx-auto">
            <a class="nav-link active" href="#">Home <span class="sr-only">(current)</span></a>
            <a class="nav-link" href="#">Features</a>
            <a class="nav-link" href="#">Pricing</a>
            <a class="nav-link disabled" href="#">Disabled</a>
        </div>
    </div>
</nav>

If you want the links exactly centered in the viewport, see the 2nd example here: http://www.codeply.com/go/RCBftzZCD8
