With Css, Use "..." For Overflowed Block of Multi-Lines

With CSS, use ... for overflowed block of multi-lines

There are also several jquery plugins that deal with this issue, but many do not handle multiple lines of text. Following works:

There also some preformance tests.

Applying an ellipsis to multiline text

I finally found a solution to do what I want.
As p a paragraphe and article the wrapper.
If you want to apply ellipsis to p depending on article height (which also depends on window height), you need to get the height of the article, the line-height of the p and then articleHeight/lineHeight to find the number of line-clamp that can be added dynamically then.

The only thing is the line-height should be declared in the css file.

Check the following code. If you change the height of the window, the line-clamp will change. Can be great to create a plug-in aiming to do that.

jsfiddle

function lineclamp() {  var lineheight = parseFloat($('p').css('line-height'));  var articleheight = $('article').height();   var calc = parseInt(articleheight/lineheight);  $("p").css({"-webkit-line-clamp": "" + calc + ""});}

$(document).ready(function() {    lineclamp();});
$( window ).resize(function() {  lineclamp();});

article {  height:60%;  background:red;  position:absolute;}
p {  margin:0;  line-height:120%;  display: -webkit-box;  -webkit-box-orient: vertical;  overflow: hidden;  text-overflow: ellipsis;}

      Call me Ishmael. Some years ago – never mind how long precisely – 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 –
      then, I account it high time to get to sea as soon as I can.

Cutoff multiple lines of text with text-overflow: ellipsis

You can use the webkit-line-clamp property - This property allows you to only show the lines you need so you can put 6 or 2 etc it is up to you. example below:

.card {  width: 400px;  height: 150px;  background: white;  border: 1px solid #EAEAEA;  box-shadow: 0px 1px 1px 0px rgba(0,0,0,0.18);  padding: 20px;}
h4 {  margin: 0;}
p {  text-overflow: ellipsis;  overflow: hidden;  display: -webkit-box;  -webkit-line-clamp: 6;  -webkit-box-orient: vertical;}

<div class="card">  <h4>Test</h4>  <p>    A test or examination (informally, exam) is an assessment intended to measure a test-taker's knowledge, skill, aptitude, physical fitness, or classification in many other topics (e.g., beliefs).[1] A test may be administered verbally, on paper, on a computer, or in a confined area that requires a test taker to physically perform a set of skills. Tests vary in style, rigor and requirements. For example, in a closed book test, a test taker is often required to rely upon memory to respond to specific items whereas in an open book test, a test taker may use one or more supplementary tools such as a reference book or calculator when responding to an item.  </p></div>

How can I do text-overflow: ellipsis on two lines?

Add a span to the container, which will hold the text:

<div class="container">
  <span>text...</span>
</span>

Add this CSS:

.container {
   overflow: hidden;
   position: relative;
   background: white;   //or other color
}

.container:after {
  content: '...';       //the ellipsis
  position: absolute;   //positioned in bottom-right
  bottom: 0;            //...
  right: 0;             //...
  padding: 0 0.3em;     //give some separation from text
  background: inherit;  //same color as container
}

.container span:after {
  content: '\0000a0';   //a space
  position: absolute;   //to cover up ellipsis if needed
  width: 1000px;        //...
  z-index: 1;           //...
  background: white;    //must match container's color.  can't use inherit here.
}

Fiddle

Resize the container, and you'll see that the ellipsis displays only as necessary.

Should work in all modern browsers.
