语法

/* 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: unset;

值

normal

使用默认的断行规则。

break-all

对于non-CJK (CJK 指中文/日文/韩文) 文本，可在任意字符间断行。

keep-all

CJK 文本不断行。 Non-CJK 文本表现同 normal。

break-word

他的效果是word-break: normal 和 overflow-wrap: anywhere  的合，不论 overflow-wrap的值是多少。

注意：与 word-break: break-word 和 overflow-wrap: break-word（详见 overflow-wrap）对比，word-break: break-word 将在文本可能溢出其容器的确切位置创建一个断点。
