CSS文字内容换行技巧:word-wrap VS. word-break

兼容 IE 和 FF 的换行 CSS 推荐样式:

最好的方式是

word-wrap:break-word; overflow:hidden;
而不是
word-wrap:break-word; word-break:break-all;
也不是
word-wrap:break-word; overflow:auto;
在 IE 下没有任何问题,在 FF 下,长串英文会被遮住超出的内容。

word-wrap同word-break的区别:

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. 必要时会触发word-break。

word-break:

normal  Default. Allows line breaking within words. 好像是只对Asian text起作用。
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 languages. This value is optimized for text that includes small amounts of Chinese, Japanese, or Korean.

总结如下:

word-wrap是控制换行的。

使用break-word时,是将强制换行。中文没有任何问题,英文语句也没问题。但是对于长串的英文,就不起作用。

break-word是控制是否断词的。

normal是默认情况,英文单词不被拆开。

break-all,是断开单词。在单词到边界时,下个字母自动到下一行。主要解决了长串英文的问题。

keep-all,是指Chinese, Japanese, and Korean不断词。即只用此时,不用word-wrap,中文就不会换行了。(英文语句正常。)
