<wbr>: The Line Break Opportunity element
The <wbr>
HTML element represents a word break opportunity—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.

Notes
On UTF-8 encoded pages, <wbr>
behaves like the U+200B ZERO-WIDTH SPACE
code point. In particular, it behaves like a Unicode bidi BN code point, meaning it has no effect on bidi-ordering: <div dir=rtl>123,<wbr>456</div>
displays, when not broken on two lines, 123,456
and not 456,123
.
For the same reason, the <wbr>
element does not introduce a hyphen at the line break point. To make a hyphen appear only at the end of a line, use the soft hyphen character entity (­
) instead.
This element was first implemented in Internet Explorer 5.5 and was officially defined in HTML5.
Example
The Yahoo Style Guide recommends breaking a URL before punctuation, to avoid leaving a punctuation mark at the end of the line, which the reader might mistake for the end of the URL.
