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>

文本溢出的要求:省略号;工作是一行的空白(pre, nowrap等)。这意味着文本永远不会到达第二行。

因此。在纯CSS中是不可能的。

编辑如果好的CSS神将实现http://www.w3.org/TR/css-overflow-3/#max-lines，我们可以在纯CSS中使用fragments(新)和max-lines(新)。还有一些关于http://css-tricks.com/line-clampin/的更多信息

编辑2 WebKit/Blink有line-clamp: -webkit-line-clamp: 2将把省略号放在第二行。

一个基于-webkit-line-clamp的纯CSS方法，适用于webkit:

@-webkit-keyframes ellipsis {/*for test*/ 0% { width: 622px } 50% { width: 311px } 100% { width: 622px } } .ellipsis { max-height: 40px;/* h*n */ overflow: hidden; background: #eee; -webkit-animation: ellipsis ease 5s infinite;/*for test*/ /** overflow: visible; /**/ } .ellipsis .content { position: relative; display: -webkit-box; -webkit-box-orient: vertical; -webkit-box-pack: center; font-size: 50px;/* w */ line-height: 20px;/* line-height h */ color: transparent; -webkit-line-clamp: 2;/* max row number n */ vertical-align: top; } .ellipsis .text { display: inline; vertical-align: top; font-size: 14px; color: #000; } .ellipsis .overlay { position: absolute; top: 0; left: 50%; width: 100%; height: 100%; overflow: hidden; /** overflow: visible; left: 0; background: rgba(0,0,0,.5); /**/ } .ellipsis .overlay:before { content: ""; display: block; float: left; width: 50%; height: 100%; /** background: lightgreen; /**/ } .ellipsis .placeholder { float: left; width: 50%; height: 40px;/* h*n */ /** background: lightblue; /**/ } .ellipsis .more { position: relative; top: -20px;/* -h */ left: -50px;/* -w */ float: left; color: #000; width: 50px;/* width of the .more w */ height: 20px;/* h */ font-size: 14px; /** top: 0; left: 0; background: orange; /**/ } <div class='ellipsis'> <div class='content'> <div class='text'>text text text text text text text text text text text text text text text text text text text text text </div> <div class='overlay'> <div class='placeholder'></div> <div class='more'>...more</div> </div> </div> </div>

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:)

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>
