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>

太遗憾了，你不能让它工作超过两行!如果元素是显示块，高度设置为2em或其他，当文本溢出时，它会显示省略号，那就太棒了!

对于单个眼线，您可以使用:

.show-ellipsis {
    overflow: hidden;
    text-overflow: ellipsis;
    white-space: nowrap;
}

对于多行，也许你可以使用Polyfill，如jQuery autoellipsis，这是在github http://pvdspek.github.com/jquery.autoellipsis/上

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。

我不是一个JS专业人士，但我想出了一些方法，你可以这样做。

HTML:

<p id="truncate">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi elementum consequat tortor et euismod. Nam commodo consequat libero vel lobortis. Morbi ac nisi at leo vehicula consectetur.</p>

然后使用jQuery将其截断为特定的字符数，但最后一个单词像这样:

// Truncate but leave last word
var myTag = $('#truncate').text();
if (myTag.length > 100) {
  var truncated = myTag.trim().substring(0, 100).split(" ").slice(0, -1).join(" ") + "…";
  $('#truncate').text(truncated);
}

结果如下所示:

我爱你，我爱你，我爱你。发病原因 基本结果tortor et…

或者，你可以像这样简单地截断它到一个特定的字符数:

// Truncate to specific character
var myTag = $('#truncate').text();
if (myTag.length > 15) {
  var truncated = myTag.trim().substring(0, 100) + "…";
  $('#truncate').text(truncated);
}

结果如下所示:

我爱你，我爱你，我爱你。发病原因 结果元素，tortoret euismod…

希望这能有所帮助。

这是jsFiddle。

这里所有的答案都是错的，他们漏掉了重要的部分，高度

.container{
    width:200px;
    height:600px;
    background:red
}
.title {
        overflow: hidden;
        line-height: 20px;
        height: 40px;
        text-overflow: ellipsis;
        display: -webkit-box;
        -webkit-line-clamp: 2;
        -webkit-box-orient: vertical;
    }
<div class="container">
    <div class="title">this is a long text you cant cut it in half</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>
