将按钮与文本标题 bootstrap 4 beta 对齐

Question

有人可以解释我如何使用 bootstrap 4 beta 将button与文本标题对齐，我确定这个例子不起作用，因为pull-left已更改。

当我尝试对齐它们时，我正在使用float-left ，但按钮不完全是它应该在的位置，所以标题应该在同一行的左侧和右侧的按钮，这是我的JSFIDDLE ，所以有人可以解释一下我是谁用新的引导程序 4 测试版来实现这一目标。

<div class="row justify-content-center">
    <div class="col-6">
      <h5><strong>BLOG TITLE GOES HERE</strong></h5>
      <div class="float-right">
        <button type="button" class="btn btn-outline-secondary">Read more</button>
      </div>
      <p class="blockquote-footer text-primary">By Branko Milosevic</p>
