如何使用 webkit-line-clamp？

Question

我有这段代码可以让我的段落变短

white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;

但问题是这段代码使所有内容都在一行中。我想用 3 行文字然后... 我在 Google 上搜索了它，发现我们有一个 WebKit 供它使用

webkit-line-clamp

但我不知道如何使用它并且它不起作用......

方法 - 1：使用text-overflow: ellipsis;

span {
    white-space: nowrap;
    text-overflow: ellipsis;
    width: 250px;
    display: block;
    overflow: hidden
}

<span>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</span>

方法 - 2：使用-webkit-line-clamp

p {
  overflow: hidden;
  display: -webkit-box;
  -webkit-line-clamp: 1;
  -webkit-box-orient: vertical; 
}

没有弹性盒的解决方案

设置文本容器的高度并相应地使用 webkit-line-clamp。

.line-clamp-3 {
  display: block;
  display: -webkit-box;
  height: 50px;
  -webkit-line-clamp: 3;
  -webkit-box-orient: vertical;
  overflow: hidden;
  text-overflow: ellipsis;
}

文本将像这样显示。
