是否有一个解决方案，添加省略号内的最后一行与流体高度(20%)div ?
我在CSS中找到了-webkit-线夹函数，但在我的情况下，行号将取决于窗口大小。
p {
width:100%;
height:20%;
background:red;
position:absolute;
}
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla sed dui felis. Vivamus vitae pharetra nisl, eget fringilla elit. Ut nec est sapien. Aliquam dignissim velit sed nunc imperdiet cursus. Proin arcu diam, tempus ac vehicula a, dictum quis nibh. Maecenas vitae quam ac mi venenatis vulputate. Suspendisse fermentum suscipit eros, ac ultricies leo sagittis quis. Nunc sollicitudin lorem eget eros eleifend facilisis. Quisque bibendum sem at bibendum suscipit. Nam id tellus mi. Mauris vestibulum, eros ac ultrices lacinia, justo est faucibus ipsum, sed sollicitudin sapien odio sed est. In massa ipsum, bibendum quis lorem et, volutpat ultricies nisi.

我有这个JSFiddle来说明这个问题。

我终于找到了做我想做的事的方法。
作为段落和文章的包装。
如果你想根据文章高度(也取决于窗口高度)对p应用省略号，你需要得到文章的高度，p的行高度，然后articleHeight/lineHeight来找到可以动态添加的线夹的数量。
唯一的问题是行高应该在css文件中声明。
检查下面的代码。如果你改变窗户的高度，线夹也会改变。创建一个旨在实现这一目标的插件是很好的。

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;
}

<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>
