 | This is a documentation subpage for Template:Word break (optional). It may contain usage information, categories and other content that is not part of the original template page. |
Creates a "word break optional" by inserting a wbr ("word break") and zwsp (zero-width space), each of which are intended to signal browsers that a linebreak is acceptable at this point if needed. (zwsp works on some browsers, wbr on others, and it seems there's no harm in just jamming both of them in here—long story.)
