html - 断字 : break-word doesn't work in flexbox

Question

我在 flexbox 元素 .learn--text 中有一个文本需要垂直居中，但是 word-break: break-word 规则不起作用。

这是当前状态

和期望的状态

.learn {
  display: flex;
  flex: 0 0 50px;
  margin-top: auto;
  align-items: stretch;
  height: 50px;
  border: 1px solid black;
  width: 250px;
}

.learn--icon {
    display: flex;
    align-items: center;
    justify-content: center;
    padding: 0 6px;
}

.learn--text {
    display: flex;
    flex-wrap: wrap;
    align-items: center;
    flex: 1;
    padding: 0 6px;
    white-space: break-spaces;
    word-break: break-word;
}

<div class="learn"><div class="learn--icon">icon</div><span class="learn--text"><a href="#">Learn more</a> about content management →
</span></div>

Answer 1

从 learn--text 中删除所有 flex 设置 - 它们将其内容“划分”为两部分，即链接和后续文本，将它们视为 flex 元素，因此视为单元。如果你擦掉它，结果如下:

.learn {
  display: flex;
  flex: 0 0 50px;
  margin-top: auto;
  align-items: center;
  height: 50px;
  border: 1px solid black;
  width: 250px;
}

.learn--icon {
    display: flex;
    align-items: center;
    justify-content: center;
    padding: 0 6px;
}

.learn--text {
    padding: 0 6px;
    white-space: break-spaces;
    word-break: break-word;
}

<div class="learn"><div class="learn--icon">icon</div><span class="learn--text"><a href="#">Learn more</a> about content management →
</span></div>
