Properties word-break:keep-all and word-break:break-all

Question

what is the difference between these two features in the p tag?

word-break: keep-all;
word-break: break-all;

Answer 1

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.
