基于-webkit-line-clamp的纯CSS方法:

@-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>

浏览器支持-如文中所述:

到目前为止，我们已经在Safari 5.0, IE 9(必须在标准模式下)， Opera 12和Firefox 15。 旧的浏览器仍然可以很好地工作，作为布局的核心 是在正常定位，边距和填充属性。如果你的 平台较老(例如Firefox 3.6, IE 8)，您可以使用该方法，但 重做渐变作为一个独立的PNG图像或DirectX过滤器。

    background: linear-gradient(to right, rgba(255, 255, 255, 0), white 50%, white); }

html:

<div class="ellipsis">
    <div>
        <p>Call me Ishmael.  Some years ago &ndash; never mind how long precisely &ndash; having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world.  It is a way I have of driving off the spleen, and regulating the circulation.  Whenever I find myself growing grim about the mouth; whenever it is a damp, drizzly November in my soul; whenever I find myself involuntarily pausing before coffin warehouses, and bringing up the rear of every funeral I meet; and especially whenever my hypos get such an upper hand of me, that it requires a strong moral principle to prevent me from deliberately stepping into the street, and methodically knocking people's hats off &ndash; then, I account it high time to get to sea as soon as I can.</p>  
    </div>
</div>

小提琴

(调整浏览器窗口大小进行测试)

有点晚了，但我想到了，我认为，是一个独特的解决方案。而不是试图通过css技巧或js插入自己的省略号，我想我会试着使用单行限制。所以我复制了每个“行”的文本，只是使用负文本缩进，以确保一行从最后一行停止的地方开始。小提琴

CSS:

#wrapper{
    font-size: 20pt;
    line-height: 22pt;
    width: 100%;
    overflow: hidden;
    padding: 0;
    margin: 0;
}

.text-block-line{
    height: 22pt;
    display: inline-block;
    max-width: 100%;
    overflow: hidden;
    white-space: nowrap;
    width: auto;
}
.text-block-line:last-child{
    text-overflow: ellipsis;
}

/*the follwing is suboptimal but neccesary I think. I'd probably just make a sass mixin that I can feed a max number of lines to and have them avialable. Number of lines will need to be controlled by server or client template which is no worse than doing a character count clip server side now. */
.line2{
    text-indent: -100%;
}
.line3{
    text-indent: -200%;
}
.line4{
    text-indent: -300%;
}

HTML:

<p id="wrapper" class="redraw">
    <span class="text-block-line line1">This text is repeated for every line that you want to be displayed in your element. This example has a max of 4 lines before the ellipsis occurs. Try scaling the preview window width to see the effect.</span>
    <span class="text-block-line line2">This text is repeated for every line that you want to be displayed in your element. This example has a max of 4 lines before the ellipsis occurs. Try scaling the preview window width to see the effect.</span>
    <span class="text-block-line line3">This text is repeated for every line that you want to be displayed in your element. This example has a max of 4 lines before the ellipsis occurs. Try scaling the preview window width to see the effect.</span>
    <span class="text-block-line line4">This text is repeated for every line that you want to be displayed in your element. This example has a max of 4 lines before the ellipsis occurs. Try scaling the preview window width to see the effect.</span>
</p>

更多的细节在小提琴。有一个问题与浏览器回流，我使用JS重绘，这样做检查它，但这是基本概念。任何想法/建议都非常感谢。

我发现这个css (scss)解决方案的工作相当好。在webkit浏览器上，它显示省略号，而在其他浏览器上，它只是截断文本。这对我的预期用途很好。

$font-size: 26px;
$line-height: 1.4;
$lines-to-show: 3;

h2 {
  display: block; /* Fallback for non-webkit */
  display: -webkit-box;
  max-width: 400px;
  height: $font-size*$line-height*$lines-to-show; /* Fallback for non-webkit */
  margin: 0 auto;
  font-size: $font-size;
  line-height: $line-height;
  -webkit-line-clamp: $lines-to-show;
  -webkit-box-orient: vertical;
  overflow: hidden;
  text-overflow: ellipsis;
}

在查看了W3规范的文本溢出后，我认为仅使用CSS是不可能的。省略号是一个新属性，所以它可能还没有得到太多的使用或反馈。

然而，这家伙似乎问了一个类似(或相同)的问题，有人能够提出一个很好的jQuery解决方案。您可以在这里演示解决方案:http://jsfiddle.net/MPkSF/

如果javascript不是一个选择，我认为你可能不走运…

为了完整起见，我想补充一下这个问题。

Opera有一个叫做-o- elliposis -lastline的非标准支持。 dotdotdot是一个很棒的jQuery插件。
