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)*$/, '...');
            });
        }
    });
}

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(' ') + '...');
     }
});

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。

这个人有最好的解决办法。css:

.multiline-ellipsis {
    display: block;
    display: -webkit-box;
    max-width: 400px;
    height: 109.2px;
    margin: 0 auto;
    font-size: 26px;
    line-height: 1.4;
    -webkit-line-clamp: 3;
    -webkit-box-orient: vertical;
    overflow: hidden;
    text-overflow: ellipsis;
}

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>

You can achieve this by a few lines of CSS and JS.

CSS:

        div.clip-context {
          max-height: 95px;
          word-break: break-all;
          white-space: normal;
          word-wrap: break-word; //Breaking unicode line for MS-Edge works with this property;
        }

JS:

        $(document).ready(function(){
             for(let c of $("div.clip-context")){
                    //If each of element content exceeds 95px its css height, extract some first 
                    //lines by specifying first length of its text content. 
                   if($(c).innerHeight() >= 95){
                        //Define text length for extracting, here 170.
                        $(c).text($(c).text().substr(0, 170)); 
                        $(c).append(" ...");
                   }
             }

        });

HTML:

        <div class="clip-context">
            (Here some text)
        </div>
