How to word-break on a dash? (8)

Given a relatively simple CSS:

div {
  width: 150px;
}
<div>
  12333-2333-233-23339392-332332323
</div>

How do I make it so that the string stays constrained to the width of 150 , and simply wraps to a newline on the hyphen?



Depending on what you want to see exactly, you can use a combination of hyphen , soft hyphen , and/or zero width space .

On a soft hyphen, your browser can word-break (adding an hyphen). On a zero width space, your browser can word break (without adding anything).

Thus, if your code is something like :

111111&shy;222222&shy;-333333&#8203;444444-&#8203;555555

then your browser will show this with no word-break :

1111112222222-33333334444444-5555555

and this will every possible word-break :

111111-
222222-
-333333
444444-
555555

Just pick up the option you need. In your case, it may be the one between 4s and 5s.


In all modern browsers * (and in some older browsers , too), the <wbr> element is the perfect tool for providing the opportunity to break long words at specific points.

To quote from that link:

The Word Break Opportunity ( <wbr> ) HTML element represents a position within text where the browser may optionally break a line, though its line-breaking rules would not otherwise create a break at that location.

Here's how it could be used to in the OP's example (or see it in action at JSFiddle ):

<div style="width: 150px;">
  12333-<wbr>2333-<wbr>233-<wbr>23339392-<wbr>332332323
</div>

* I've tested it in IE9, IE10, and the latest versions of Chrome, Firefox, and Opera, and Safari.

div {
  width: 150px;
}
<div>
  12333-<wbr>2333-<wbr>233-<wbr>23339392-<wbr>332332323
</div>


In this specific instance (where your string is going to contain hyphens) I'd transform the text to this server-side:

<div style="width:150px;">
  <span>12333-</span><span>2333-</span><span>233-</span><span>23339392-</span><span>332332323</span>
</div>


Replace your hyphens with this:

&shy;

It's called a "soft" hyphen.

div {
  width: 150px;
}
<div>
  12333&shy;2333&shy;233&shy;23339392&shy;332332323
</div>


The non-breaking hyphen works well.

HTML Entity (decimal)

&#8209;

You can use 0 width space after hyphen character:

div {
  width: 150px;
}
<div>
  12333-&#8203;2333-&#8203;233-&#8203;23339392-&#8203;332332323
</div>

if You want line break before hyphen use &#8203;- instead.


Your example works as expected in Google Chrome, Safari (Windows), and IE8. The text breaks out of the 150px box in Firefox 3 and Opera 9.5.

Additionally &shy; won't work for your example, as it will either:

  • work when word-breaking but when not word-breaking not display any hyphens, or

  • work when not word-breaking but display two hyphens when word-breaking since it adds a hyphen on a break.
