Bootstrap 4 Multiple fixed-top navbars

Question

Is it possible to have multiple fixed-top navbars in Bootstrap 4 showing under each other?

The 1 currently overlays the other which is not what I want.

Answer 1

Both navs can use sticky-top (instead of fixed-top) so you don't have to set the padding on the body.

The second navbar should use top so that the padding will only show when it nears the top.

padding-top will create padding before it hits the top navbar when the padding is necessary.

Answer 2

Yes, it's possible but you have to position the 2nd one accordingly. The height of the Navbar is ~56px.

.fixed-top-2 {
    margin-top: 56px;
}

body {
    padding-top: 105px;
}

<nav class="navbar navbar-toggleable-sm bg-faded navbar-light fixed-top fixed-top-2">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbar1">
        <span class="navbar-toggler-icon"></span>
    </button>
    <a href="/" class="navbar-brand">One</a>
    <div class="navbar-collapse collapse" id="navbar1">
        <ul class="navbar-nav">
            ..
        </ul>
    </div>
</nav>

<nav class="navbar navbar-toggleable-sm bg-inverse navbar-inverse fixed-top">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbar2">
        <span class="navbar-toggler-icon"></span>
    </button>
    <a href="/" class="navbar-brand">Two</a>
    <div class="navbar-collapse collapse" id="navbar2">
        <ul class="navbar-nav">
            ..
        </ul>
    </div>
</nav>

In some scenarios, it may be better to use a single fixed-top DIV to contain both.
