在 material-design-lite 中的全宽卡之间添加垂直 space

Question

如何在MDL卡组件之间添加space？

<div class="demo-card-event mdl-card mdl-shadow--2dp">
  <div class="mdl-card__title mdl-card--expand">
    <h4>
      Featured event:<br>
      May 24, 2016<br>
      7-11pm
    </h4>
  </div>
  <div class="mdl-card__actions mdl-card--border">
    <a class="mdl-button mdl-button--colored mdl-js-button mdl-js-ripple-effect">
      Add to Calendar
    </a>
    <div class="mdl-layout-spacer"></div>
    <i class="material-icons">event</i>
  </div>
</div>

<div class="demo-card-event mdl-card mdl-shadow--2dp">
  <div class="mdl-card__title mdl-card--expand">
    <h4>
      Featured event:<br>
      May 24, 2016<br>
      7-11pm
    </h4>
  </div>
  <div class="mdl-card__actions mdl-card--border">
    <a class="mdl-button mdl-button--colored mdl-js-button mdl-js-ripple-effect">
      Add to Calendar
    </a>
    <div class="mdl-layout-spacer"></div>
    <i class="material-icons">event</i>
  </div>
</div>

这是卡片组件，卡片之间没有 space 它们完全首尾相连。

是否有任何内置 class 可以添加 space 或我们需要手动添加，或者我的代码是否有任何错误。

尝试添加 mdl-layout-spacer class 仍然无效。

这是添加网格的正确方法吗？

<div class="mdl-grid" style="max-width: 90%;">
    <div class="mdl-cell mdl-cell--9-col mdl-card mdl-shadow--4dp">

    </div>

    <div class="mdl-cell mdl-cell--3-col mdl-typography--text-center">

        <div class="mdl-grid">
            <div class="mdl-cell mdl-cell--12-col mdl-card mdl-shadow--2dp">
                <div class="mdl-card__title mdl-card--expand">
                    <h4>
                        Featured event:<br>

                        7-11pm
                    </h4>
                </div>
                <div class="mdl-card__actions mdl-card--border">
                    <a class="mdl-button mdl-button--colored mdl-js-button mdl-js-ripple-effect">
                        Add to Calendar
                    </a>
                    <div class="mdl-layout-spacer"></div>
                    <i class="material-icons">event</i>

您可以在卡片周围添加行包装器并向卡片添加一个单元格 class，或者将每张卡片包裹在一个单元格中 class，具体取决于您想要的效果。
