line-break

The line-break CSS property sets how to break lines of Chinese, Japanese, or Korean (CJK) text when working with punctuation and symbols.

/* Keyword values */
line-break: auto;
line-break: loose;
line-break: normal;
line-break: strict;
line-break: anywhere;

/* Global values */
line-break: inherit;
line-break: initial;
line-break: unset;

Syntax

Values

auto
Break text using the default line break rule.
loose
Break text using the least restrictive line break rule. Typically used for short lines, such as in newspapers.
normal
Break text using the most common line break rule.
strict
Break text using the most stringent line break rule.
anywhere

There is a soft wrap opportunity around every typographic character unit, including around any punctuation character or preserved white spaces, or in the middle of words, disregarding any prohibition against line breaks, even those introduced by characters with the GL, WJ, or ZWJ character class or mandated by the word-break property. The different wrapping opportunities must not be prioritized. Hyphenation is not applied.

Formal definition

Initial value auto
Applies to all elements
Inherited yes
Computed value as specified
Animation type discrete

Formal syntax

auto | loose | normal | strict | anywhere

Examples

Setting text wrapping

See whether the text is wrapped before "々", "ぁ" and "。".
