word-break

The word-break CSS property sets whether line breaks appear wherever the text would otherwise overflow its content box.

Try it

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: revert-layer;
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 Deprecated: Has the same effect as word-break: normal and overflow-wrap: anywhere, regardless of the actual value of the overflow-wrap property.

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).

Note: While word-break: break-word is deprecated, it has the same effect, when specified, as word-break: normal and overflow-wrap: anywhere — regardless of the actual value of the overflow-wrap property.
