对多行文字应用省略号[重复]

Question

有没有办法在流体高度为20%的div中的最后一行添加省略号？

我在CSS中找到了-webkit line clamp函数，但在我的例子中，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. Maecenas scelerisque sodales ipsum a hendreritLorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla sed dui felis. Vivamus vitae pharetra nisl, eget fringilla elit. Ut nec est sapien.

请检查此css中是否有多行文字的省略号

body {
  margin: 0;
  padding: 50px;
}

/* mixin for multiline */
.block-with-text {
  overflow: hidden;
  position: relative;
  line-height: 1.2em;
  max-height: 6em;
  text-align: justify;
  margin-right: -1em;
  padding-right: 1em;
}
.block-with-text:before {
  content: '...';
  position: absolute;
  right: 0;
  bottom: 0;
}
.block-with-text:after {
  content: '';
  position: absolute;
  right: 0;
  width: 1em;
  height: 1em;
  margin-top: 0.2em;
  background: white;
}

<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>

如果要应用省略号（…）对于一行文本，CSS使用text overflow属性使其变得简单。这仍然有点棘手（由于所有要求–请参见下文），但文本溢出使其成为可能且可靠。

然而，如果你想在多行文字上使用省略号——就像这里的情况一样——那就别指望有什么乐趣了。CSS没有标准的方法来实现这一点，而且解决方法是随意的。

使用文本溢出，省略号可以应用于单行文本。必须满足以下CSS要求：

• 必须具有宽度、最大宽度或弹性基础

因此，这将起作用：

p {
  width: 200px;
  white-space: nowrap;
  overflow: hidden;
  display: inline-block;
  text-overflow: ellipsis;
  border: 1px solid #ddd;
  margin: 0;
}

只需增加-webkit线夹：4；增加行数

p {
    display: -webkit-box;
    max-width: 200px;
    -webkit-line-clamp: 4;
    -webkit-box-orient: vertical;
    overflow: hidden;
}
