Show first line of a paragraph

I have a DIV with 开发者_C百科a multi-line paragraph.

Is there any way (maybe using jQuery) to only show the first line of the paragraph and hide the others?

Here is a way (sort of) by making the paragraph white-on-white except the :first-line of it: http://jsbin.com/usora4/2/edit

Snippet of CSS:

p { color: white; }
p:first-line { color: black; }

It has been awhile since this was answered but seeing there is no example here is one that works pretty well:

<div style="width:200px">
<div>
    This is above the paragraph.
</div>
<div class="excerpt">
    This is my text. It has many lines. This is my text.
    It has many lines.This is my text. It has many lines.
    This is my text. It has many lines. This is my text.
    It has many lines.
</div>
<div>
    This is below the paragraph.
</div>
</div>


<style type="text/css">
div.excerpt { height:2.2em; overflow:hidden; }
div.excerpt:hover { height:auto; }
</style>

There is not an outright way to do this by specifying the first line. I would suggest changing the height of the DIV using CSS to only show the first line. It would seem to me to be the simplest solution. If you then want to change to show the whole line with javascript just use it to change the height of the DIV back to 100%.

EDIT: I stand corrected, I was not aware that there was a first-line pseudo class. However changing the height may still be the simplest way.

No need for JavaScript, measuring height, or changing visibility. Just set the paragraph to display inline and not to wrap its text. You'll want to set the overflow on the parent div to "hidden" so the remaining lines in the paragraph don't spill out.

#wrap {
    overflow: hidden;   
    text-overflow: ellipsis; 
}
p {
    display: inline;
    white-space: nowrap;
}​

Just adding this here as an idea. It allows you to show and hide the text with a text box. CSS only.

p.bar { font-size:0; margin:0;padding:10px;background: #ddd; -webkit-transition: font-size .25s;transition: font-size .25s;
}
p.bar:first-line { font-size:20px; }
input:checked + label  + p.bar {font-size: 20px;}

<input id="foo" type="checkbox"><label for="foo">show</label><p class="bar">Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas.

Determine the height of your line and set the height of the div such that only one line is shown, and set the div's overflow attribute to hidden.

I haven't tried it, but you should be able to do a little better using visibility, e.g.

<div class="excerpt">
   This is my text.  It has many lines. This is my text.  
   It has many lines. This is my text. It has many lines. 
   This is my text.  It has many lines. This is my text.  
   It has many lines.
</div>

and then setting up a style

div.excerpt { visibility: hidden; }
div.excerpt:first-line { visibility: visible; }
