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