html - 使同级元素具有相同的宽度会破坏其中的文本

Question

我正在尝试设置 div 的宽度，它的内容为其中 user-title 段落的宽度。这是 HTML 和 CSS:

.panel {
  margin-bottom: 20px;
  width: auto;
  display: inline-flex;
  flex-direction: column;
  box-shadow: 0 2px 4px 0 #C6C2BF;
  padding: 0.5rem 1rem 1rem;
}

.user-title {
  display: flex;
}

.panel>div {
  display: flex;
  flex-direction: column;
}

.panel>div>p {
  display: flex;
  flex-grow: 1;
  width: 0;
}

<div class="panel">
  <p class="user-title">Date 08.03.2018 User: Joe Doe</p>
  <div>
    <p>Some long text in the paragraph that is wider than the title above it</p>
    <p>Another shorter text</p>
  </div>
</div>

这种设置使元素占据 user-title 元素的宽度，但是，文本分成多行。我怎样才能解决这个问题？这是fiddle .

如果我在这里没有完全弄错的话，使用 CSS 实现跨浏览器的唯一方法是将 display: inline-block 与 display: table-row/显示:表格标题。

.panel {
  margin-bottom: 20px;
  display: inline-block;
  box-shadow: 0 2px 4px 0 #C6C2BF;
  padding: 0.5rem 1rem 1rem;
}

.user-title {
  display: table-row;
}

.panel > div {
  display: table-caption;
  caption-side: bottom;
}

<div class="panel">
    <p class="user-title">Date 08.03.2018 User: Joe Doe</p>
    <div>
      <p>Some long text in the paragraph that is wider than the title above it</p>
      <p>Another shorter text</p>
    </div>
</div>

如果你不关心 IE，那么使用 width: 0; min-width: 100%; 在 .parent div 上。

请注意，我在 Edge v.16、Firefox v.58 和 Chrome v.64 上测试成功，但我不能说它是否适用于 Safari。

    padding: 0.5rem 1rem 1rem;
}

.panel > div {
  width: 0;
  min-width: 100%;
}

<div class="panel">
    <p class="user-title">Date 08.03.2018 User: Joe Doe</p>
    <div>
      <p>Some long text in the paragraph that is wider than the title above it</p>
      <p>Another shorter text</p>
    </div>
</div>

经过反复试验，我在 IE11 和 Edge/Firefox/Chrome 上都能正常工作

.panel {
    margin-bottom: 20px;
    display: inline-flex;
    flex-direction: column;
    box-shadow: 0 2px 4px 0 #C6C2BF;
    padding: 0.5rem 1rem 1rem;
}

.panel > div {
  width: 0;
  min-width: 100%;
  display: flex;           /*  for IE11  */
  flex-wrap: wrap;         /*  for IE11  */
}

.panel > div > p {
  flex: 100%;              /*  for IE11  */
}

<div class="panel">
    <p class="user-title">Date 08.03.2018 User: Joe Doe</p>
    <div>
      <p>Some long text in the paragraph that is wider than the title above it</p>
      <p>Another shorter text</p>
    </div>
</div>
