您可以使用 text-overflow：ellipsis height 。

像这样

  .truncate 
 {
 width：250px; 
 white-space：nowrap; 
 overflow：hidden; 
 text-overflow：ellipsis; 
 height：100px; 
} 
 

通过使用文本溢出，可以显示您的输出而不使用javascript。 / p>

Is there a CSS-only way (no JavaScript/jQuery) to only show the first two lines and, if there are three or more lines, hide the extra lines and show an ellipsis?

For example, how can I take this fiddle:

http://jsfiddle.net/0yyr3e63/

...and make it look like this?

Lorem Ipsum Dolor
Sit Amet Consectetur

Ut Enim Ad Minim
Veniam Quis Nostrud...

Duis Aute Irure
Dolor In...

Thanks in advance.

You can use text-overflow:ellipsis property with height.

Like this

.truncate 
{
width: 250px;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
height:100px;
}

By using text-overflow, you can display your output without using javascript.
