省略号在CSS网格布局中不起作用

Question

我在使用css网格的div中使用elipsis属性时遇到了一些问题.

如果我直接在网格子项中设置elipsis属性它可以工作,但是当在网格中的div内部使用它时它不起作用.

你可以看到这里有什么问题:

body{
  text-align:center;
}
.container{
  width: 300px;
  background-color:#ccc;
  margin-left:auto;
  margin-right:auto;
}

#grid{
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
}

#grid > div{
  border:1px solid #000;
  padding:5px;
}

.elipsis{
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
}

<h2>This works</h2>
<p>as selipsis class is directly in col-2 div</p>
<div class="container">
  <div id="grid">
    <div class="col-1">A</div>
    <div class="col-2 elipsis">
      B B B B B B B B B B B B B B B B B
    </div>
    <div class="col-3">C</div>
  </div>
</div>

<h2>This doesn't worl</h2>
<p>as selipsis class is in a div inside col-2 div</p>
<div class="container">
  <div id="grid">
    <div class="col-1">A</div>
    <div class="col-2">
      <div class="elipsis">B B B B B B B B B B B B B B B B B</div>
    </div>
    <div class="col-3">C</div>
  </div>
</div>

谢谢.

这似乎通过应用于第二种情况overflow: hidden的容器来解决div.

body {
  text-align: center;
}

.container {
  width: 300px;
  background-color: #ccc;
  margin-left: auto;
  margin-right: auto;
}

#grid {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
}

#grid>div {
  border: 1px solid #000;
  padding: 5px;
}

.elipsis {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

.col-2b {
  overflow: hidden;
}

<h2>This works</h2>
<p>as selipsis class is directly in col-2 div</p>
<div class="container">
  <div id="grid">
    <div class="col-1">A</div>
    <div class="col-2 elipsis">
      B B B B B B B B B B B B B B B B B
    </div>
    <div class="col-3">C</div>
  </div>
</div>

<h2>This doesn't worl</h2>
<p>as selipsis class is in a div inside col-2 div</p>
<div class="container">
  <div id="grid">
    <div class="col-1">A</div>
    <div class="col-2 col-2b">
      <div class="elipsis">B B B B B B B B B B B B B B B B B</div>
    </div>
    <div class="col-3">C</div>
  </div>
</div>
