The WBR element is a stand-alone element which indicates to the browser
where a particular word is ALLOWED to be broken. This does not
necessarily mean that the word WILL be broken at this point - it is just
a guide for the browser. Within the context of the NOBR element, the WBR
element EXPLICITLY tells the browser where to put the word/line break.
Attributes
This element does not accept any attributes
Example
<nobr>This is a really
super-duper, extremely long run of no<wbr>break text
which should be broken only where we tell it to</nobr>
Note: Style Sheet attributes are
not listed for the WBR element because of a caveat listed in the
Cascading Style Sheets specification for the BR element -
It states that the break element is a 'Replaced Element' that is
replaced in the document with a line break and thus has no
properties. Although WBR is not in any standards yet that the
CSS1 authors would consider, WBR offers a similar effect to
BR so it is placed in the same class with respect to style
sheet treatment.
