当我把文本放入这样的容器中时,文本的顶部被截断(pen):

<div class="align-items-center d-flex justify-content-center mb-3 overflow-auto" style="background-color: red; height: 5rem">
  <figure class="mb-0" style="background-color: orange">
    <div class="d-flex justify-content-center text-center" style="background-color: yellow">
      Hickory dickory dock.<br>
      The mouse ran up the clock.<br>
      The clock struck one,<br>
      The mouse ran down,<br>
      Hickory dickory dock.
    </div>
  </figure>
</div>

当我像这样将Bootstrap类转换为内联样式时,文本的顶部没有被截断(pen):

<div style="align-items: center; background-color: red; display: flex; height: 5rem; justify-content: center; margin-bottom: 1rem; overflow: auto">
   <figure style="background-color: orange; margin-bottom: 0">
     <div style="background-color: yellow; display: flex; justify-content: center; text-align: center">
       Hickory dickory dock.<br>
       The mouse ran up the clock.<br>
       The clock struck one,<br>
       The mouse ran down,<br>
       Hickory dickory dock.
     </div>
   </figure>
 </div>

我的问题是:

  • 为什么?
  • 我怎样才能保留Bootstrap类而不删除内容的顶部?

这是由于height: 5removerflow-auto类的组合应用于外部div元素。height属性将元素的高度限制为5 rem,并且overflow-auto属性在内容溢出元素时创建一个可滚动容器。在本例中,由于内容大于5 rem,因此创建了一个可滚动容器。但是内容的顶部被隐藏,因为它在容器的可见区域之外。
要保留Bootstrap类,您可以删除height属性,然后将overflow-y设置为visible-这将阻止创建可滚动容器。overflow-x属性将保留为auto,以便在需要时创建水平条。这种组合可确保整个内容可见,而不会切断顶部。

<div class="align-items-center d-flex justify-content-center mb-3 overflow-auto" style="background-color: red; overflow-y: visible;">
  <figure class="mb-0" style="background-color: orange">
    <div class="d-flex justify-content-center text-center" style="background-color: yellow">
      Hickory dickory dock.<br>
      The mouse ran up the clock.<br>
      The clock struck one,<br>
      The mouse ran down,<br>
      Hickory dickory dock.
    </div>
  </figure>
</div>
