引导行溢出 - HTML

在HTML中，当文本或其他内容超出了其容器的宽度时，会发生引导行溢出（wrapping overflow）。通常情况下，文本或内容会自动换行到下一行，以适应容器的大小。但如果设置了overflow-wrap或word-wrap属性，则可以控制文本是否换行，以及在何处断开。

overflow-wrap属性

overflow-wrap属性指定了如何在单词或连字符处进行换行：

<div style="width: 200px; overflow-wrap: break-word;">
  This is a very very very very very very very very very very very very very very very very very very very very very very very very very very very very long line of text.
</div>

上面的代码片段中，overflow-wrap属性被设置为break-word，这意味着单词将在必要时被拆开，以适应容器的宽度。结果将是一个坚实的块，其容器的宽度为200px，该文本已被换行并适应该容器。

word-wrap属性

word-wrap属性类似于overflow-wrap属性，但它也可以在单词内部进行换行，而不仅仅是在单词边缘：

<div style="width: 200px; word-wrap: break-word;">
  This is a very very very very very very very very very very very very very very very very very very very very very very very very very very very very long line of text.
</div>

在这个例子中，word-wrap属性也被设置为break-word，但是由于它在单词内部也可以换行，所以这段文本可以在单词内部进行换行，从而适应容器的大小。

总结

引导行溢出是HTML中的一个常见问题，但是使用overflow-wrap和word-wrap属性可以帮助开发人员更好地控制文本的换行和断行。无论是拆分单词还是在单词内部进行换行，这些属性可以帮助确保文本适应其容器的大小，从而提高用户体验。
