How to align content bottom on Bootstrap 4 col

You can use align-items-end from the new Bootstrap 4 flexbox utilities…

<div class="container">
    <hr>
    <div class="row align-items-end">
        <div class="col-md-6">
            © BusinessName 2017.
        </div>
        <div class="col-md-3">

            <br>

Also, auto margins work inside flexbox. There you could use mt-auto (margin-top:auto) to “push” the col-* to the bottom.
