word-break

Theword-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; /* non-standard */ 

/* Global values */
word-break: inherit;
word-break: initial;
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: To prevent overflow, normally unbreakable words may be broken at arbitrary points if there are no otherwise acceptable break points in the line.

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).

Formal syntax

normal | break-all | keep-all | break-word
