While displaying a long word, some times it might broken into next line at wrong location. By using "wbr" tag, we can control the the places long word can be broken into next line.
Suppose to display a word "FailOverClustering", if the word breaks at "Fai" its not desirable. If we want to break this word only at words, "Fail","Over","Clustering" we can use "wbr" tag to control it.
