Is there a way to word-wrap long words in a div? 6 answers

I have this piece of HTML

<div id='permalink_section'>
  <a href="here goes a very long link">here goes a very very long link</a>
</div>

with, for now, this CSS

div#permalink_section { width: 960px }

The link text can be very long and it overflows the div when it's length does exceed the div width. Is there a way to force the link to break and go on the next line when its width exceeds the div width?

回答1:

The following is a cross browser compatible solution.

#permalink_section
{
    white-space: pre-wrap; /* css-3 */    
    white-space: -moz-pre-wrap; /* Mozilla, since 1999 */
    white-space: -pre-wrap; /* Opera 4-6 */    
    white-space: -o-pre-wrap; /* Opera 7 */    
    word-wrap: break-word; /* Internet Explorer 5.5+ */
}

回答2:

if you're okay with css3, there's a property for that:

word-wrap:break-word

回答3:

Works for Internet Explorer 8+, Firefox 6+, iOS 4.2, Safari 5.1+ and Chrome 13+.

CSS

.word-wrap {
    /* Warning: Needed for oldIE support, but words are broken up letter-by-letter */
    -ms-word-break: break-all;
    word-break: break-all;
    /* Non standard for webkit */
    word-break: break-word;

    -webkit-hyphens: auto;
    -moz-hyphens: auto;
    -ms-hyphens: auto;
    hyphens: auto;
}

Source: kenneth.io

SCSS

@mixin word-wrap() {
    word-break:     break-word;
    -webkit-hyphens: auto;
    -moz-hyphens:    auto;
    hyphens:         auto;
}

wrap link inside another div with smaller width

<html>
<head><title></title>

<style type="text/css">
div#permalink_section { width: 960px }

</style>
</head>
<body>
<div id='permalink_section'>
<div id="linkwrap" style="width:100px">
  <a href="here goes a very long link">here goes a very very long link</a>
  </div>
</div>
</body>
</html>

回答5:

div#permalink_section
{   
    width:960px;
    overflow:hidden;
}

div#permalink_section
{   
    width:960px;
    word-wrap:break-word
}

or use javascript to truncate the length of the link's text, replacing the end with "..."

Working example of the JS method: http://jsfiddle.net/fhCYX/3/

I didn't have much luck with the solution in the accepted answer, so I tried a different approach. On load, I pad all slashes in the anchor text with spaces: "/" --> " / ". Most links don't have slashes and so this does nothing, and most links that do have them are hyperlinks, and these look okay with this substitution, and then the links do wrap correctly.

    $('a').each(function ()
    {
        //get the content
        var content = $(this).html();

        //a regex to find all slashes
        var rgx = new RegExp('/', 'g');

        //do the replacement
        content = content.replace(rgx, " / ")

        //the previous step also affects http:// (where present), so fix this back up
        content = content.replace('http: /  / ', 'http://');

        //set the content back into the element
        $(this).html(content);
    });

overflow:hidden seems to be the key to making an element of size:auto break-word correctly

<ul class="list">
<li class="item">
    <div class="header">
      <div class="content"></div>
    </div>
    <div class="body ">
<p>Loremipsumdolorsitametconsecteturadipisicingelitseddoeiusmodtemporincididuntutlaboreetdoloremagnaaliqua.</p>
    </div>
</li>

</ul>


.list {
    border: 1px solid black;
    margin: 50px;
}

.header {
    float:left;
}

.body {
    overflow: hidden;
}

.body p {
    word-wrap: break-word;
}

.header .content {
    background: #DDD;
    width: 80px;
    height: 30px;
}

That example includes a left float as I was trying to achieve a media-object like layout.

Unfortunately if you try to use table-cell elements it breaks again :(

回答8:

You could also wrap each letter of the link in <span></span> using javascript for example.

<a href="http://foo.bar"><span>f</span><span>o</span><span>o</span></a>

But I would go for the css3 approach.
