word-break
The word-break CSS property sets whether line breaks appear wherever the text would otherwise overflow its content box.
Syntax
/* Keyword values */ word-break: normal; word-break: break-all; word-break: keep-all; word-break: break-word; /* deprecated */ /* Global values */ word-break: inherit; word-break: initial; word-break: revert; word-break: unset;
The word-break property is specified as a single keyword chosen from the list of values below.
Values
normal-  
Use the default line break rule.
 break-all-  
To prevent overflow, word breaks should be inserted between any two characters (excluding Chinese/Japanese/Korean text).
 keep-all-  
Word breaks should not be used for Chinese/Japanese/Korean (CJK) text. Non-CJK text behavior is the same as for
normal. - 
break-word -  
Has the same effect as
word-break: normalandoverflow-wrap: anywhere, regardless of the actual value of theoverflow-wrapproperty. 
Note: In contrast to word-break: break-word and overflow-wrap: break-word (see overflow-wrap), word-break: break-all will create a break at the exact place where text would otherwise overflow its container (even if putting an entire word on its own line would negate the need for a break).
