bootstrap 4对齐按钮在中心

Question

我有点卡住如何居中对齐我有一个按钮组:

<section>
  <div class="d-inline mx-auto">
    <a class="btn btn-outline-primary" href="#">Home</a>
    <a class="btn btn-outline-primary" href="#">Traffic</a>
    <a class="btn btn-outline-primary" href="#">MAC Monitoring</a>
    <a class="btn btn-outline-primary" href="#">Alert Logging</a>
    <a class="btn btn-outline-primary" href="#">Diameter Server</a>
    <a class="btn btn-outline-primary" href="#">Maintenance Mode</a>
  </div>
</section>

我试图添加d-inline和mx-auto但它不起作用.我不熟悉图书馆,所以有人可以指出我正确的方向吗？

只需使用margin:auto它与bootstrap 4一起工作

.center{margin:auto;}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" rel="stylesheet"/>
<section class="row">
  <div class="center">
    <a class="btn btn-outline-primary" href="#">Home</a>
    <a class="btn btn-outline-primary" href="#">Traffic</a>
    <a class="btn btn-outline-primary" href="#">MAC Monitoring</a>
    <a class="btn btn-outline-primary" href="#">Alert Logging</a>
    <a class="btn btn-outline-primary" href="#">Diameter Server</a>
    <a class="btn btn-outline-primary" href="#">Maintenance Mode</a>
  </div>
</section>

或者你可以这样使用mx-auto..

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" rel="stylesheet"/>
<section class="row">
  <div class="mx-auto">
    <a class="btn btn-outline-primary" href="#">Home</a>
    <a class="btn btn-outline-primary" href="#">Traffic</a>
    <a class="btn btn-outline-primary" href="#">MAC Monitoring</a>
    <a class="btn btn-outline-primary" href="#">Alert Logging</a>
    <a class="btn btn-outline-primary" href="#">Diameter Server</a>
    <a class="btn btn-outline-primary" href="#">Maintenance Mode</a>
  </div>
</section>
