I am trying to center my Container in the middle of the page using Bootstrap 4.
<section id="film">
    <div class="container">
        <div class="row">
            <div class="col-md-6">
                <div class="card-body">
                    <img src="images\laravel.jpg" class="img-fluid">
                </div>
            </div>
            <div class="col-md-6">
                <div class="card-body">
                    <div class="d-flex align-items-center">
                        <img src="images\logo.png" class="img-fluid">
                    </div>
                </div>
            </div>
        </div>
    </div>
</section>
The justify-content-center aligns the form horizontally, but I can't figure out how to align it vertically. I have tried to use align-items-center and align-self-center, but it doesn't work.
What am I missing?
