糟糕的CSS不支持跨浏览器多行夹紧，只有webkit似乎在推动它。

你可以尝试使用一个简单的Javascript省略号库，比如github上的Ellipsity，源代码非常干净和小，所以如果你确实需要做任何额外的改变，它应该很容易。

也许这个能帮到你们。多线椭圆与工具提示悬停。 https://codepen.io/Anugraha123/pen/WOBdOb

<div>
     <p class="cards-values">Lorem ipsum dolor sit amet,   consectetur adipiscing elit. Nunc aliquet lorem commodo, semper mauris nec, suscipit nisi. Nullam laoreet massa sit amet leo malesuada imperdiet eu a augue. Sed ac diam quis ante congue volutpat non vitae sem. Vivamus a felis id dui aliquam tempus
      </p>
      <span class="tooltip"></span>
</div>

在浏览了整个互联网并尝试了很多这些选项后，唯一能确保它正确覆盖支持i.e.的方法是通过javascript，我创建了一个循环函数来查看需要多行截断的post项目。

*注意我使用Jquery，并要求你的post__items类有一个固定的最大高度。

// loop over post items
$('.post__items').each(function(){
    var textArray = $(this).text().split(' ');
    while($(this).prop('scrollHeight') > $(this).prop('offsetHeight')) {
        textArray.pop();
        $(this).text(textArray.join(' ') + '...');
     }
});

请检查下面的代码纯css技巧与适当的对齐，支持所有浏览器

.block-with-text { overflow: hidden; position: relative; line-height: 1.2em; max-height: 103px; text-align: justify; padding: 15px; } .block-with-text:after { content: '...'; position: absolute; right: 15px; bottom: -4px; background: linear-gradient(to right, #fffff2, #fff, #fff, #fff); } <p class="block-with-text">The Hitch Hiker's Guide to the Galaxy has a few things to say on the subject of towels. A towel, it says, is about the most massivelyuseful thing an interstellar hitch hiker can have. Partly it has great practical value - you can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapours; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a mini raft down the slow heavy river Moth; wet it for use in hand-to-hand-combat; wrap it round your head to ward off noxious fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a mindboggingly stupid animal, it assumes that if you can't see it, it can't see you - daft as a bush, but very ravenous); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough. More importantly, a towel has immense psychological value. For some reason, if a strag (strag: non-hitch hiker) discovers that a hitch hiker has his towel with him, he will automatically assume that he is also in possession of a toothbrush, face flannel, soap, tin of biscuits, flask, compass, map, ball of string, gnat spray, wet weather gear, space suit etc., etc. Furthermore, the strag will then happily lend the hitch hiker any of these or a dozen other items that the hitch hiker might accidentally have "lost". What the strag will think is that any man who can hitch the length and breadth of the galaxy, rough it, slum it, struggle against terrible odds, win through, and still knows where his towel is is clearly a man to be reckoned with.</p>

我只是在这个概念上玩了一下。基本上，如果你可以从你的最后一个字符中删除一个像素，这里是一个纯css和html的解决方案:

其工作方式是将一个div绝对定位在视口的可视区域之下。我们希望随着内容的增长，div向上偏移到可见区域。如果内容增长太多，我们的div将偏移过高，所以我们的内容可以增长的高度的上限。

HTML:

<div class="text-container">
  <span class="text-content">
    PUT YOUR TEXT HERE
    <div class="ellipsis">...</div> // You could even make this a pseudo-element
  </span>
</div>

CSS:

.text-container {
    position: relative;
    display: block;
    color: #838485;
    width: 24em;
    height: calc(2em + 5px); // This is the max height you want to show of the text. A little extra space is for characters that extend below the line like 'j'
    overflow: hidden;
    white-space: normal;
}

.text-content {
  word-break: break-all;
  position: relative;
  display: block;
  max-height: 3em;       // This prevents the ellipsis element from being offset too much. It should be 1 line height greater than the viewport 
}

.ellipsis {
  position: absolute;
  right: 0;
  top: calc(4em + 2px - 100%); // Offset grows inversely with content height. Initially extends below the viewport, as content grows it offsets up, and reaches a maximum due to max-height of the content
  text-align: left;
  background: white;
}

我已经在Chrome、FF、Safari和IE 11上进行了测试。

你甚至可以用一些CSS魔术来缓解字符的突然切断。

编辑:我猜这强加的一件事是word-break: break-all，否则内容不会扩展到视口的最末端。：(

不幸的是，在CSS的当前状态下没有。

省略号渲染有一个先决条件:空白:nowrap，这实际上意味着:省略号只在单行文本容器上绘制。
