我想在特定宽度的div内仅包含两行内的文本。如果文本超出两行的长度，那么我想显示elipses。 有没有办法用CSS做到这一点？
e.g。

of text in only two line...

如果您设置元素的line-height和height，并设置overflow:hidden;，则可以使用CSS将输出限制为两行文本：
#someDiv {
line-height: 1.5em;
height: 3em; /* height is 2x line-height, so two lines will display */
overflow: hidden; /* prevents extra lines from being visible */
}
或者，您可以使用CSS text-overflow和white-space属性添加省略号，但这只适用于单行。
#someDiv {
line-height: 1.5em;
height: 3em;
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;
width: 100%;
}
一个演示：
实现多行文本和省略号似乎是javascript的领域。

我见过的最好的只有CSS而且响应来自Mobify Developer Blog - CSS Ellipsis: How to Manage Multi-Line Ellipsis in Pure CSS：
CSS：
html, body, p { margin: 0; padding: 0; font-family: sans-serif;}
.ellipsis {
overflow: hidden;
height: 200px;
line-height: 25px;
margin: 20px;
border: 5px solid #AAA; }
.ellipsis:before {
content:"";
float: left;
width: 5px; height: 200px; }
.ellipsis > *:first-child {
float: right;
width: 100%;
margin-left: -5px; }
.ellipsis:after {
content: "\02026";
box-sizing: content-box;
-webkit-box-sizing: content-box;
-moz-box-sizing: content-box;
float: right; position: relative;
top: -25px; left: 100%;
width: 3em; margin-left: -3em;
padding-right: 5px;
text-align: right;
background: -webkit-gradient(linear, left top, right top,
from(rgba(255, 255, 255, 0)), to(white), color-stop(50%, white));
background: -moz-linear-gradient(to right, rgba(255, 255, 255, 0), white 50%, white);

background: linear-gradient(to right, rgba(255, 255, 255, 0), white 50%, white); }
HTML：
<div class="ellipsis">
<div class="blah">
<p>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.</p>

另一种简单快捷的解决方案
.giveMeEllipsis {
overflow: hidden;
text-overflow: ellipsis;
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: N; /* number of lines to show */
line-height: X; /* fallback */
max-height: X*N; /* fallback */
}

我认为仅限CSS的解决方案text-overflow: ellipsis仅适用于一行，因此您将无法使用此路线：
.yourdiv {
line-height: 1.5em; /* Sets line height to 1.5 times text size */
height: 3em; /* Sets the div height to 2x line-height (3 times text size) */
width: 100%; /* Use whatever width you want */
white-space: normal; /* Wrap lines of text */
overflow: hidden; /* Hide text that goes beyond the boundaries of the div */
text-overflow: ellipsis; /* Ellipses (cross-browser) */
-o-text-overflow: ellipsis; /* Ellipses (cross-browser) */
}

仅适用于Webkit的CSS解决方案
.multiLineLabel {
display: inline-block;
box-sizing: border-box;
white-space: pre-line;
word-wrap: break-word;
}
.multiLineLabel .textMaxLine {
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: 2;
overflow: hidden;
}
/* Only for DEMO */
.multiLineLabel.maxWidth {
width: 100px;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="multiLineLabel">
<span class="textMaxLine">This text is going to wrap automatically in 2 lines in case the width of the element is not sufficiently wide.</span>

通常，单行截断非常简单
.truncate-text {
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}
两行截断有点棘手，但可以用css完成这个例子是sass。
@mixin multiLineEllipsis($lineHeight: 1.2rem, $lineCount: 2, $bgColor: white, $padding-right: 0.3125rem, $width: 1rem, $ellipsis-right: 0) {
overflow: hidden; /* hide text if it is more than $lineCount lines */
position: relative; /* for set '...' in absolute position */
line-height: $lineHeight; /* use this value to count block height */
max-height: $lineHeight * $lineCount; /* max-height = line-height * lines max number */
padding-right: $padding-right; /* place for '...' */
white-space: normal; /* overwrite any white-space styles */
word-break: break-all; /* will break each letter in word */
text-overflow: ellipsis; /* show ellipsis if text is broken */
&::before {
content: '...'; /* create the '...'' points in the end */
position: absolute;
right: $ellipsis-right;
bottom: 0;
}
&::after {
content: ''; /* hide '...'' if we have text, which is less than or equal to max lines and add $bgColor */
position: absolute;
right: 0;
width: $width;
height: 1rem * $lineCount;
margin-top: 0.2rem;
background: $bgColor; /* because we are cutting off the diff we need to add the color back. */
}
}

请参阅http://jsfiddle.net/SWcCt/。
只需设置line-height height的一半：
line-height:20px;
height:40px;
当然，为了使text-overflow: ellipsis工作，您还需要：
overflow:hidden;
white-space: pre;
