在 class h-50 上，我如何使用 bootstrap 4

将文本与 div 的底部对齐

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css" integrity="sha384-WskhaSGFgHYWDcbwN70/dfYBj47jz9qbsMId/iRN3ewGhXQFZCSftd1LZCfmhktB" crossorigin="anonymous">
<div style='height:300px;border:1px solid #333;'>
                <div class="bg-primary d-inline-block h-25">Height 25%</div>
                <div class="bg-primary d-inline-block text-bottom h-50"><span class='text-bottom'>Height 50%</span></div>
                <div class="bg-primary d-inline-block h-75">Height 75%</div>
                <div class="bg-primary d-inline-block h-100">Height 100%</div>
                <div class="bg-primary d-inline-block h-auto">Height Auto</div>
            </div>

Bootstrap 4 中的一种可能性是在 h-50 div 上使用 d-inline-flex flex-column，然后在 div 上使用 d-flex align-items-end h-100将要对齐的跨度包装在底部：
