将省略号应用于多行文本

Question

有没有解决方案在div中的最后一行添加省略号,流体高度(20%)？

我-webkit-line-clamp在CSS中找到了这个函数,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.

Maecenas scelerisque sodales ipsum a hendrerit.</p>

我有这个JSFiddle来说明这个问题. https://jsfiddle.net/96knodm6/

Answer 1

如果要将省略号(...)应用于单行文本,CSS使该text-overflow属性更容易.它仍然有点棘手(由于所有要求 - 见下文),但text-overflow使其成为可能和可靠.

但是,如果你想在多行文字上使用省略号- 就像这里的情况那样 - 那么不要期望有任何乐趣.CSS没有标准的方法来执行此操作,并且解决方法很容易被击中.

单行文本的省略号

使用text-overflow,省略号可以应用于单行文本.必须满足以下CSS要求:

• 必须有width,max-width或flex-basis
• 一定有 white-space: nowrap
• 必须具有overflow除以外的价值visible
• 必须是display: block或inline-block (或功能等同,如弹性项目).

所以这将有效:

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

<p>
  This is a test of CSS <i>text-overflow: ellipsis</i>.

</p>

jsFiddle版本

但是,尝试删除width,或让overflow默认visible,或删除white-space: nowrap,或使用块容器元素以外的东西,并且省略号失败.

这里text-overflow: ellipsis有一个很大的好处:对多行文字没有影响.(white-space: nowrap仅此要求就消除了这种可能性.)

p {
    width: 200px;
    /* white-space: nowrap; */
    height: 90px; /* new */
    overflow: hidden;
    display: inline-block;
    text-overflow: ellipsis;
    border: 1px solid #ddd;
    margin: 0;
}

请检查此css以获取省略号到多行文本

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>

只需增加-webkit-line-clamp:4; 增加行数

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

线夹是一种专有的无证件CSS(webkit):https://caniuse.com/#feat=css-line-clamp,因此它目前仅适用于少数浏览器.

Answer 5

我终于找到了做我想做的解决方案.作为pparagraphe和article包装.如果你想申请省略号p视article高(这也依赖于窗口的高度),你需要得到height的article,该line-height的p,然后articleHeight/lineHeight找到的数量line-clamp可以动态地补充说,然后.

唯一的事情是line-height应该在css文件中声明.

请检查以下代码.如果更改窗口的高度,line-clamp则会更改.可以很好地创建一个旨在实现这一目标的插件.

的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;
}

这个人有最好的解决方案.只有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;
}

Answer 7

我刚刚用这个概念玩了一下.基本上,如果你可能有一个像素左右切断你的最后一个字符,这里是一个纯粹的CSS和HTML解决方案:

这种方式的工作方式是将div绝对定位在视口的可视区域下方.随着内容的增长,我们希望div可以偏移到可见区域.如果内容增长太多,我们的div将偏移太高,因此上限我们的内容可以增长.

HTML:

<div class="text-container">
  <span class="text-content">
    PUT YOUR TEXT HERE
    <div class="ellipsis">...</div> // You could even make this a pseudo-element
  </span>
</div>

CSS:

.text-container {
    position: relative;
    display: block;
    color: #838485;
    width: 24em;
    height: calc(2em + 5px); // This is the max height you want to show of the text. A little extra space is for characters that extend below the line like 'j'
    overflow: hidden;
    white-space: normal;
}

.text-content {
  word-break: break-all;
  position: relative;
  display: block;
  max-height: 3em;       // This prevents the ellipsis element from being offset too much. It should be 1 line height greater than the viewport 
}

.ellipsis {
  position: absolute;
  right: 0;
  top: calc(4em + 2px - 100%); // Offset grows inversely with content height. Initially extends below the viewport, as content grows it offsets up, and reaches a maximum due to max-height of the content
  text-align: left;
  background: white;
}

我在Chrome,FF,Safari和IE 11中对此进行了测试.

你可以在这里查看:http://codepen.io/puopg/pen/vKWJwK

你甚至可以通过一些CSS魔法来缓解角色的突然切断.

编辑:我想这有一个问题就是分词:break-all,否则内容不会延伸到视口的最后.:(

Answer 8

不幸的是没有CSS的当前状态.

省略号渲染具有white-space:nowrap有效的先决条件:省略号仅在单行文本容器上绘制.

Answer 9

用户使用以下公式：

overflow: hidden;
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: 2; //put number of line here

Answer 10

我在他们的主页上看了YouTube如何解决它并对其进行了简化：

.multine-ellipsis {
  -webkit-box-orient: vertical;
  display: -webkit-box;
  -webkit-line-clamp: 2;
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: normal;
}

这将允许两行代码，然后附加省略号。
