如果有人试图让线夹在flexbox中工作，那就有点棘手了——特别是当您使用非常长的单词进行折磨测试时。这段代码片段中唯一真正的区别是min-width: 0;在包含截断文本的伸缩项中，以及换行:断字;。向https://css-tricks.com/flexbox-truncated-text/致敬。免责声明:在写这个答案的时候，Chrome以外的浏览器支持很差。然而，从那时起，情况可能有所改善。

.flex-parent { display: flex; } .short-and-fixed { width: 30px; height: 30px; background: lightgreen; } .long-and-truncated { margin: 0 20px; flex: 1; min-width: 0;/* Important for long words! */ } .long-and-truncated span { display: inline; -webkit-line-clamp: 3; text-overflow: ellipsis; overflow: hidden; display: -webkit-box; -webkit-box-orient: vertical; word-wrap: break-word;/* Important for long words! */ } <div class="flex-parent"> <div class="flex-child short-and-fixed"> </div> <div class="flex-child long-and-truncated"> <span>asdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasdasd</span> </div> <div class="flex-child short-and-fixed"> </div> </div>

这是一个纯css的好例子。

.container{ width: 200px; } .block-with-text { overflow: hidden; position: relative; line-height: 1.2em; max-height: 3.6em; text-align: justify; margin-right: -1em; padding-right: 1em; } .block-with-text+.block-with-text{ margin-top:10px; } .block-with-text:before { content: '...'; position: absolute; right: 0; bottom: 0; } .block-with-text:after { content: ''; position: absolute; right: 0; width: 1em; height: 1em; margin-top: 0.2em; background: white; } <div class="container"> <div class="block-with-text"> 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 </div> <div class="block-with-text"> Lorem Ipsum is simply dummy text of the printing and typesetting industry </div> <div class="block-with-text"> Lorem Ipsum is simply </div> </div>

纯css方式用省略号修饰多行文本

调整文本容器的高度， 用-webkit-line-clamp控制断线:2;

.block-ellipsis {
  display: block;
  display: -webkit-box;
  max-width: 100%;
  height: 30px;
  margin: 0 auto;
  font-size: 14px;
  line-height: 1;
  -webkit-line-clamp: 2;
  -webkit-box-orient: vertical;
  overflow: hidden;
  text-overflow: ellipsis;
}

我以前遇到过这个问题，没有纯css解决方案

这就是为什么我开发了一个小型库来处理这个问题(以及其他问题)。标准库提供了用于建模和执行字母级文本呈现的对象。例如，您可以模拟带有任意限制的text-overflow:省略号(不一定只有一行)

我以前使用过jquery - condensed -plugin，看起来它可以做你想做的事情。如果不是，有不同的插件可以满足您的需求。

编辑:给你做了一个演示-注意，我在演示中链接了jquery. condene .js，这是有魔力的，所以完全归功于该插件的作者:)

如果有人正在使用SASS/SCSS，并偶然发现了这个问题-也许这个mixin可以帮助:

@mixin line-clamp($numLines : 1, $lineHeight: 1.412) {
  overflow: hidden;
  text-overflow: -o-ellipsis-lastline;
  text-overflow: ellipsis;
  display: block;
  /* autoprefixer: off */
  display: -webkit-box;
  -webkit-line-clamp: $numLines;
  -webkit-box-orient: vertical;
  max-height: $numLines * $lineHeight + unquote('em');
}

这只在webkit浏览器中添加省略号。休息只是把它切断了。
