No line-break after a hyphen
You could also wrap the relevant text with
<span style="white-space: nowrap;"></span>
You can also do it "the joiner way" by inserting "U+2060
Word Joiner".
If Accept-Charset
permits, the unicode character itself can be inserted directly into the HTML output.
Otherwise, it can be done using entity encoding. E.g. to join the text red-brown
, use:
red-⁠brown
or (decimal equivalent):
red-⁠brown
. Another usable character is "U+FEFF
Zero Width No-break Space"[ 1 ]:
red-brown
and (decimal equivalent):
red-brown
[1]: Note that while this method still works in major browsers like Chrome, it has been deprecated since Unicode 3.2.
Comparison of "the joiner way" with "U+2011
Non-breaking Hyphen":
The word joiner can be used for all other characters, not just hyphens.
When using the word joiner, most renderers will rasterize the text identically. On Chrome, FireFox, IE, and Opera, the rendering of normal hyphens, eg:
a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r-s-t-u-v-w-x-y-z
is identical to the rendering of normal hyphens (with U+2060 Word Joiner), eg:
a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r-s-t-u-v-w-x-y-z
while the above two renders differ from the rendering of "Non-breaking Hyphen", eg:
a‑b‑c‑d‑e‑f‑g‑h‑i‑j‑k‑l‑m‑n‑o‑p‑q‑r‑s‑t‑u‑v‑w‑x‑y‑z
. (The extent of the difference is browser-dependent and font-dependent. E.g. when using a font declaration of "
arial
", Firefox and IE11 show relatively huge variations, while Chrome and Opera show smaller variations.)
Comparison of "the joiner way" with <span class=c1></span>
(CSS .c1 {white-space:nowrap;}
) and <nobr></nobr>
:
The word joiner can be used for situations where usage of HTML tags is restricted, e.g. forms of websites and forums.
On the spectrum of presentation and content, majority will consider the word joiner to be closer to content, when compared to tags.
• As tested on Windows 8.1 Core 64-bit using:
• IE 11.0.9600.18205
• Firefox 43.0.4
• Chrome 48.0.2564.109 (Official Build) m (32-bit)
• Opera 35.0.2066.92
IE8/9 render the non-breaking hyphen mentioned in CanSpice's answer longer than a typical hyphen. It is the length of an en-dash instead of a typical hyphen. This display difference was a deal breaker for me.
As I could not use the CSS answer specified by Deb I instead opted to use no break tags.
<nobr>e-mail</nobr>
In addition I found a specific scenario that caused IE8/9 to break on a hyphen.
- A string contains words separated by non-breaking spaces -
- Width is limited
- Contains a dash
IE renders it like this.
The following code reproduces the problem pictured above. I had to use a meta tag to force rendering to IE9 as IE10 has fixed the issue. No fiddle because it does not support meta tags.
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="X-UA-Compatible" content="IE=9" />
<meta charset="utf-8"/>
<style>
body { padding: 20px; }
div { width: 300px; border: 1px solid gray; }
</style>
</head>
<body>
<div>
<p>If there is a - and words are separated by the whitespace code &nbsp; then IE will wrap on the dash.</p>
</div>
</body>
</html>
Try using the non-breaking hyphen ‑
. I've replaced the dash with that character in your jsfiddle, shrunk the frame down as small as it can go, and the line doesn't split there any more.
