Hi @Justin Espiritu,

This code works correctly for me:

  <header class="h-100">
    <mdb-navbar SideClass="navbar fixed-top navbar-expand-lg navbar-dark scrolling-navbar intro-fixed-nav" [containerInside]="false">
      <mdb-navbar-brand>
        <a class="logo navbar-brand" href="#">
          <strong>Navbar</strong>
        </a>
      </mdb-navbar-brand>
      <links>
        <ul class="navbar-nav mr-auto">
          <li class="nav-item active waves-light" mdbWavesEffect>
            <a class="nav-link">Home
              <span class="sr-only">(current)</span>
            </a>
          </li>
          <li class="nav-item waves-light" mdbWavesEffect>
            <a class="nav-link">Link</a>
          </li>
          <li class="nav-item waves-light" mdbWavesEffect>
            <a class="nav-link">Profile</a>
          </li>
        </ul>
      </links>
    </mdb-navbar>
    <!-- Main -->
    <div class="view intro-2">
      <div class="full-bg-img">
        <div class="mask rgba-purple-light flex-center">
          <div class="container text-center white-text wow fadeInUp">
            <h2>This Navbar is fixed and transparent</h2>
            <br>
            <h5>It will always stay visible on the top, even when you scroll down</h5>
            <p>Navbar's background will switch from transparent to solid color while scrolling down</p>
            <br>
            <p>Full page intro with background image will be always displayed in full screen mode, regardless of device </p>
          </div>
        </div>
      </div>
    </div>
    <!-- /.Main -->
  </header>

  <!--Main Layout-->
  <main class="text-center py-5">

And SCSS (But you have paste this code for your global file. styles.scss)

.view {
    background: url("https://mdbootstrap.com/img/Photos/Others/img (40).jpg")no-repeat center center;
    background-size: cover;
    height: 100vh;
}

.navbar {
    background-color: transparent;
}

.top-nav-collapse {
    background-color: #4285F4;
}

@media only screen and (max-width: 768px) {
    .navbar {
        background-color: #4285F4;
    }
}

Can you test my code?

Best, Konrad.

html,
body {
  height: 100%;
  max-width: 100%;
  overflow-x: hidden;
}

.top-nav-collapse {
  background-color: #4285F4;
}

@media only screen and (max-width: 768px) {
  .navbar {
