增加-webkit-线夹:4;增加行数:

p { 显示： -网络套件盒; 最大宽度：200px; -网络套件线夹： 4; -网络套件盒方向：垂直; 溢出：隐藏; } <p>Lorem ipsum dolor sit amet， novum menandri adrivalrium ad vim， ad his persius nostrud conclusionemque.Ne qui atomorum pericula honestatis.Te usu quaeque detracto， idque nulla pro ne， ponderum invidunt eu duo.Vel velit tincidunt in， nulla bonorum id eam， vix ad fastidii consequat definitionem.</p>

线夹是一种专有的无文档的CSS (webkit): https://caniuse.com/#feat=css-line-clamp，所以它目前只适用于少数浏览器。

删除重复的“显示”属性+删除不必要的“文本溢出:省略号”。

p{
line-height: 20px;
width: 157px;
white-space: nowrap; 
overflow: hidden;
text-overflow: ellipsis;
}

或者我们可以通过使用和高度和溢出来限制行。

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>

对此，我提出了自己的解决方案:

/*this JS code puts the ellipsis (...) at the end of multiline ellipsis elements
 *
 * to use the multiline ellipsis on an element give it the following CSS properties
 * line-height:xxx
 * height:xxx (must line-height * number of wanted lines)
 * overflow:hidden
 *
 * and have the class js_ellipsis
 * */

//do all ellipsis when jQuery loads
jQuery(document).ready(function($) {put_ellipsisses();});

//redo ellipsis when window resizes
var re_ellipsis_timeout;
jQuery( window ).resize(function() {
    //timeout mechanism prevents from chain calling the function on resize
    clearTimeout(re_ellipsis_timeout);
    re_ellipsis_timeout = setTimeout(function(){ console.log("re_ellipsis_timeout finishes"); put_ellipsisses(); }, 500);
});

//the main function
function put_ellipsisses(){
    jQuery(".js_ellipsis").each(function(){

        //remember initial text to be able to regrow when space increases
        var object_data=jQuery(this).data();
        if(typeof object_data.oldtext != "undefined"){
            jQuery(this).text(object_data.oldtext);
        }else{
            object_data.oldtext = jQuery(this).text();
            jQuery(this).data(object_data);
        }

        //truncate and ellipsis
        var clientHeight = this.clientHeight;
        var maxturns=100; var countturns=0;
        while (this.scrollHeight > clientHeight && countturns < maxturns) {
            countturns++;
            jQuery(this).text(function (index, text) {
                return text.replace(/\W*\s(\S)*$/, '...');
            });
        }
    });
}

经过多次尝试，我终于用混合的js / css来处理多行和单行溢出。

CSS3代码:

.forcewrap { // single line ellipsis
  -ms-text-overflow: ellipsis;
  -o-text-overflow: ellipsis;
  text-overflow: ellipsis;
  overflow: hidden;
  -moz-binding: url( 'bindings.xml#ellipsis' );
  white-space: nowrap;
  display: block;
  max-width: 95%; // spare space for ellipsis
}

.forcewrap.multiline {
  line-height: 1.2em;  // my line spacing 
  max-height: 3.6em;   // 3 lines
  white-space: normal;
}

.manual-ellipsis:after {
  content: "\02026";      // '...'
  position: absolute;     // parent container must be position: relative
  right: 10px;            // typical padding around my text
  bottom: 10px;           // same reason as above
  padding-left: 5px;      // spare some space before ellipsis
  background-color: #fff; // hide text behind
}

我简单地检查js代码的溢出在divs，像这样:

function handleMultilineOverflow(div) {
    // get actual element that is overflowing, an anchor 'a' in my case
    var element = $(div).find('a'); 
    // don't know why but must get scrollHeight by jquery for anchors
    if ($(element).innerHeight() < $(element).prop('scrollHeight')) {
        $(element).addClass('manual-ellipsis');
    }
}

html中的用法示例:

<div class="towrap">
  <h4>
    <a class="forcewrap multiline" href="/some/ref">Very long text</a>
  </h4>
</div>

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。
