I haven't looked at your site, but it looks like you need to add the -ms-hyphens
prefix to your css. You have the -webkit
and -moz
but no -ms
:
-ms-hyphens: none;
See here for more info: http://msdn.microsoft.com/en-us/library/ie/hh771871(v=vs.85).aspx
Also, after looking into it a bit more, it looks like Opera doesn't support this, and neither do most mobile browsers: http://caniuse.com/css-hyphens - Just a heads up in case you come across that down the road.
