How to use flex box to have BS4 nav-item fill navbar height with text centered vertically-Twitter bootstrap

I am trying to use flexbox to customize a bootstrap 4 navbar. I want the nav-items to fill the full height of the navbar div while keeping their contents centered vertically and the spacing between the 3 horizontally links consistent (using justify-content-around). I have not been successful using the code below. Is it possible?

Any help would be appreciated.

<nav id="mainNav" class="navbar navbar-expand-md navbar-light bg-primary pt-0 pb-0">
  <a class="navbar-brand d-none d-sm-block mr-auto my-2" href="#"><img class="img-fluid" src="https://via.placeholder.com/139x60"></a>

  <div class="collapse navbar-collapse mx-5" id="navbarCollapse">

    <!-- Stetch these virticall -->
    <ul class="navbar-nav nav-fill w-100 align-items-start">
      <li class="nav-item active">
        <a class="nav-link bg-danger" href="#">Shop Now<span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Why Buy From Us</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Contact Us</a>
      </li>

    </ul>

    <div class="input-group">
      <input class="form-control form-control-sm" type="text" placeholder="Search" aria-label="Search">
      <div class="input-group-append">
        <span class="input-group-text"><i class="far fa-search"></i></span>
      </div>
    </div>

    It appears that in order to get bootstrap navbar links to fill the full height of the navbar and center the text vertically, I needed to add a targetable container inside the .nav-link class to apply align-self: center to.

    I used a span tag and decided to use CSS rather than inline classes to keep the code cleaner and in my case limited it to only the #mainNav ID.

    Wondering if there is an even cleaner way to do this without the extra span tag.

    #mainNav,
.collapse,
.nav-link {
  display: flex;
  align-items: stretch;
}

#mainNav .navbar-nav {
  display: flex;
  justify-content: space-around;
  width: 100%;
}

#mainNav .nav-item {
  display: flex;
}

#mainNav .nav-link span {
  align-self: center;
}

    Try add class “my-0 p-0” in your brand image

    Then, add approximately “height: 3.7em” to your links and add the “py-3” class to them
