The <WBR> element stands for Word BReak. This is for the very rare case when a <NOBR> section requires an exact break. Also, it can be used any time the browser can be helped by telling it where a word is allowed to be broken. The <WBR> element does not force a line break (<BR> does that) it simply lets the browser know where a line break is allowed to be inserted if needed.

NOTE : The <WBR> Element is supported only by Netscape and the Internet Explorer.
