Text-overflow: 省略号导致弹性项目溢出弹性容器

Question

我在弹性容器中有两列。其中一列（橙色列）包含一个头像，其宽度应恰好为容器的 10%。

另一列（蓝色列）包含面板，面板的标题可能很长，所以我应该通过 css 截断它。这张照片显示了我的期望：

我的期望：

但是当我尝试 text-overflow: ellipsis 时，我的第二行变得比 flex 容器更宽。这是此行为的示例：

.container {
  background: #ddd;
  width: 400px;
  height: 200px;
  padding: 10px;
  display: flex;
}

.row1 {
  background: red;
  flex-basis: 10%;
  flex-shrink: 0;
}

.row2 {
  background: blue;
  flex-basis: 90%;
  margin-left: 10px;
  padding: 10px;
  display: flex;
}

.panel {
  background: green;
  flex-basis: 50%;
  overflow: hidden;
}

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

<div class="container">

  <div class="row1">
  </div>

  <div class="row2">
    <div class="panel">
      <div class="panel-title">
        <span>Lorem ipsum. Lorem ipsum. Lorem ipsum. Lorem ipsum. Lorem ipsum. Lorem ipsum. Lorem ipsum.</span>
      </div>
    </div>
  </div>
</div>

我该如何解决这个问题？

Answer 1

使用 width 代替 flex-basis。因为在 this Documentation 他们提到了

9.9.3. Flex Item Intrinsic Size Contributions

The main-size min-content/max-content contribution of a flex item is its outer min-content/max-content size, clamped by its flex base size as a maximum (if it is not growable) and/or as a minimum (if it is not shrinkable), and then further clamped by its min/max main size properties.

不要忘记将宽度 calc(90% - 30px) 设置为 row2 宽度

.container {
  background: #ddd;
  width: 400px;
  height: 200px;
  padding: 10px;
  display: flex;
}

.row1 {
    background: red;
    /* flex-basis: 10%; */
    width: 10%;
    flex-shrink: 0;
}

.row2 {
    background: blue;
    /* flex-basis: 90%; */
    width: calc(90% - 30px);
    margin-left: 10px;
    padding: 10px;
    display: flex;
}

.panel {
  background: green;
  flex-basis: 50%;
  overflow: hidden;
}

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

<div class="container">

  <div class="row1">
  </div>

  <div class="row2">
    <div class="panel">
      <div class="panel-title">
        <span>Lorem ipsum. Lorem ipsum. Lorem ipsum. Lorem ipsum. Lorem ipsum. Lorem ipsum. Lorem ipsum.</span>
      </div>
    </div>
  </div>
</div>
