css 自动换行 word-break:break-all和word-wrap:break-word
1,word-break:break-all 例如div宽200px,它的内容就会到200px自动换行,如果该行末端有个英文单词很长(congratulation等),它会把单词截断,变成该行末端为conra(congratulation的前端部分),下一行为tulation(conguatulation)的后端部分了。 2,word-wrap:break-word 例子与上面一样,但区别就是它会把congratulation整个单词看成一个整体,如果该行末端宽度不够显示整个单词,它会自动把整个单词放到下一行,而不会把单词截断掉的。 3,word-break;break-all 支持版本:IE5以上 该行为与亚洲语言的 normal 相同。也允许非亚洲语言文本行的任意字内断开。该值适合包含一些非亚洲文本的亚洲文本。 WORD-WRAP:break-word 支持版本:IE5.5以上 内容将在边界内换行。如果需要,词内换行( word-break )也将发生。表格自动换行,避免撑开。 word-break : normal | break-all | keep-all 参数: normal : 依照亚洲语言和非亚洲语言的文本规则,允许在字内换行 break-all : 该行为与亚洲语言的normal相同。也允许非亚洲语言文本行的任意字内断开。该值适合包含一些非亚洲文本的亚洲文本 keep-all : 与所有非亚洲语言的normal相同。对于中文,韩文,日文,不允许字断开。适合包含少量亚洲文本的非亚洲文本 语法: word-wrap : normal | break-word 参数: normal : 允许内容顶开指定的容器边界 break-word : 内容将在边界内换行。如果需要,词内换行(word-break)也行发生说明:设置或检索当当前行超过指定容器的边界时是否断开转行。 对应的脚本特性为wordWrap。请参阅我编写的其他书目。 语法: table-layout : auto | fixed 参数: auto : 默认的自动算法。布局将基于各单元格的内容。表格在每一单元格读取计算之后才会显示出来。速度很慢 fixed : 固定布局的算法。在这算法中,水平布局是仅仅基于表格的宽度,表格边框的宽度,单元格间距,列的宽度,而和表格内容无关说明:设置或检索表格的布局算法。对应的脚本特性为tableLayout。 建议:word-break 用3C检测会显示问题的,导致百度快照也会出问题-这个属性OPERA FIREFOX 浏览器也不支持 word-break属性可以用white-space:normal;来代替,这样在FireFox和IE下就都能正确换行,而且要注意,单词间的空格不能用 来代替,不然不能正确换行。 我在网站上试验过确实不支持,你可以再W3C验证一下
