Word-break: Break-all and word-wrap: Break-word can automatically wrap the content of a container such as Div.

Their differences are:

1. Word-break: Break-ALL: for example, if the DIV width is PX, its content will be automatically wrapped in PX. If the end of the line has a long English word (congratulation, etc ), it truncates the word and converts it to the backend part of the row whose end is CONRA (congratulation) and the next row is tulation (conguatulation.

2. Word-wrap: the break-word example is the same as above, but the difference is that it regards the entire word congratulation as a whole. If the end width of the row is insufficient, it automatically puts the entire word in the next line, instead of truncating the word.

3. Word-break; break-all supports version: ie5 or above, which is the same as normal in the Asian language. It also allows non-Asian text lines to be broken in any word. This value is suitable for Asian texts that contain non-Asian texts. Word-wrap: Break-word supported version: ie5.5 and above will be wrapped in the boundary. If necessary, the line feed (Word-break) also occurs. Automatic table line breaks to avoid opening. Word-break: normal | break-All | keep-All parameter: Normal: line breaks are allowed according to the text rules of the Asian and non-Asian languages.
Break-ALL: this behavior is the same as that of the Asian language normal. It also allows non-Asian text lines to be broken in any word. This value is suitable for Asian text keep-all that contains some non-Asian text: it is the same as normal in all non-Asian languages. Chinese, Korean, and Japanese cannot be disconnected. It is applicable to non-Asian text syntax that contains a small amount of Asian text: Word-wrap: normal | break-word parameter: Normal: allows the content to open the specified container boundary break-word: the content will wrap in the boundary. If necessary, word-break also indicates whether to disconnect or retrieve the line break when the line breaks beyond the boundary of the specified container.

Compatible with wrap CSS recommended styles for IE and FF
The best way is

Word-wrap: Break-word; overflow: hidden;

Instead

Word-wrap: Break-word; Word-break: Break-all;

Neither

Word-wrap: Break-word; overflow: auto;

There is no problem in IE. In ff, long strings of English will be overwritten.

Differences between word-wrap and word-break

Word-wrap:

Normal default. content exceeds the boundaries of its container.

Break-word content wraps to next line, and a word-break occurs when necessary. If necessary, the word-break is triggered.

Word-break:

Normal default. Allows line breaking within words. It seems to work only for Asian text.

Break-All behaves the same as normal for Asian text, yet allows the line to break arbitrarily for non-Asian text. this value is suited to Asian text that contains some excerpts of non-Asian text.

Keep-all does not allow word breaking for Chinese, Japanese, and Korean. functions the same way as normal for all non-Asian ages. this value is optimized for text that contains des small amounts of Chinese,
Japan, or Korean.

Summary:

Word-wrap controls line breaks.

When break-word is used, a line break is forced. There is no problem with Chinese and no problem with English statements. However, long strings do not work in English.

Break-word controls whether words are disconnected.

Normal is the default condition, and English words are not separated.

Break-all, which is a broken word. When a word reaches the boundary, the next letter automatically goes to the next line. It mainly solves the problem of long strings in English.

Keep-All refers to continuous Words in Chinese, Japanese, and Korean. That is to say, in this case, word-wrap is not used, and the Chinese text will not wrap. (The English statement is normal .)
IE:

Use Word-wrap: Break-word; all are normal.

FF:

If none of the two are used, Chinese will not cause any problems. There are no problems with English statements. However, long strings may cause problems in English.

To solve the problem of long strings in English, word-wrap: Break-word; Word-break: Break-all; is generally used ;. However, this method causes the words in Common English statements to be disconnected (also in IE ).

At present, the main problem is that long strings of English and English words are disconnected. In fact, long strings of English are just a long word.

That is, should an English word be disconnected? It is obvious that the problem should not be broken.

For long strings of English, it is malicious and you don't have to worry about it. However, we also need to find some way to prevent it from making the container large.

With: overflow: auto; ie, the long string is automatically folded. FF, the long string will be covered.

Therefore, in summary, the best way is word-wrap: Break-word; overflow: hidden; instead of word-wrap: Break-word; Word-break: Break-all ;.

Word-wrap: Break-word; overflow: auto; no problem in IE. In ff, long strings will be covered by some content.
