Bootstrap 4 navbar - no height on mobile

Question

How to set the initial height of bootstrap 4 in all viewports to 80 pixels?

I tried "min-height: 80px" in ".navbar", but the navigation bar is broken.

Sass code:

$navbar-bg:             #26f3fd;
$navbar-height:         80px;

.navbar {
    background-color: $navbar-bg;
    min-height: $navbar-height;
}

Html code:

<nav class="navbar navbar-toggleable-md navbar-light bg-faded" id="main-navbar" data-toggle="sticky-onscroll">
    <button class="navbar-toggler navbar-toggler-left" type="button" data-toggle="collapse" data-target="#navbar-content" aria-controls="navbar-content" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse justify-content-md-center" id="navbar-content">
    <ul class="navbar-nav">
        <li class="nav-item active">
            <a class="nav-link" href="<?= esc_url(home_url('/')); ?>">Accueil</a>
        </li>
    </ul>
</div>

The problem is that your navbar does not contain navbar-brand, so the height collapses when the navbar stacks vertically.

This is a known issue that will be fixed in beta: https://github.com/twbs/bootstrap/pull/22230

The workaround is to include an empty navigational text or navigational mark.

<nav class="navbar navbar-toggleable-md navbar-light bg-faded py-3" id="main-navbar">
    <button class="navbar-toggler navbar-toggler-left" type="button" data-toggle="collapse" data-target="#navbar-content" aria-controls="navbar-content" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <span class="navbar-text">&nbsp;</span>
    <div class="collapse navbar-collapse justify-content-md-center" id="navbar-content">
      <ul class="navbar-nav">
        <li class="nav-item active">
          <a class="nav-link" href="#">Accueil</a>
        </li>
      </ul>
    </div>
</nav>
