word-break: break-all;、word-break: keep-all; 、word-wrap: break-word;和white-space:nowrap;都有什么作用

     小颖最近心情不好,心情不好就容易做傻事,所以昨天就干了件傻事

小颖昨天脑子一抽去拔罐了,拔完我就~~~~~~~~~~~~疼死宝宝了,昨晚一晚都没睡好,都不敢平躺,难受一晚上,早上到公司后困得啊,也是傻得没谁了。

     好啦言归正传,今天小颖给大家分享下,小颖理解的word-break: break-all;、word-break: keep-all; 、word-wrap: break-word;和white-space:nowrap;。下面就一起来看看代码吧!

先看看页面效果图吧:

css代码:

    <style media="screen">
        .main {
            width: 600px;
            margin: 0 auto;
        }

        .txt-one,
        .txt-two,
        .txt-three,
        .txt-four {
            overflow: hidden;

        }

        .txt-two {
            background-color: rgba(244, 67, 54, 0.38);
        }

        .txt-three {

        .no-word-warp-ch,
        .no-word-warp-eg {

        }

        .word-break-ch,
        .word-break-eg {
          word-break: break-all;
          /*允许任意非CJK(Chinese/Japanese/Korean)文本间的单词断行。*/
          word-break: keep-all;
          /*不允许CJK(Chinese/Japanese/Korean)文本中的单词换行,只能在半角空格或连字符处换行。非CJK文本的行为实际上和normal一致。*/
        }

        .word-warp-ch,
        .word-warp-eg {
            word-wrap: break-word;
            /*内容将在边界内换行。如果需要,单词内部允许断行。*/
            /*white-space:nowrap;     用于处理元素内的空白,使得元素里的内容只在一行内显示。*/}
    </style>

我们先来看看word-break: break-all;word-break: keep-all;

                                                               图(1)

                                                     图(2)

1word-break: break-all;   允许任意非CJK(Chinese/Japanese/Korean)文本间的单词断行。

2word-break: keep-all; 不允许CJK(Chinese/Japanese/Korean)文本中的单词换行,只能在半角空格或连字符处换行。非CJK文本的行为实际上和normal一致。

图中的左侧div小颖没有给其加   word-break 样式,大家通过对比可以看出图1中给div设置了   word-break: break-all; 后div里面的内容中文右侧和左侧对比发现数字500部分换行显示;英文右侧和左侧对比发现英语单词  successsurprisingGlobalMobilereferred等英文单词因为当前行显示不完,直接将显示不完的部分换行显示,而没有整个单词换行显示。

2 中给div 设置了   word-break: keep-all; 只能在半角空格或连字符处换行,比如:伴随着中国移动(微博)成功牵头5G系统设计, 这段话因为太长所以,在 “”处换行。当小颖将 “)”删除后,这段话则在“(”处换行,再比如   中国移动总裁李跃透露,  这段话在   Forum以下简称MBBF)上,  之后但因  中国移动总裁李跃透露,  这段话太长所以在 “”处换行。

再来看看  word-wrap: break-word;

小颖给图中左侧div没有设置   word-wrap: break-word; 右侧div设置了  word-wrap: break-word;,不过左右两侧的中英文显示并没有什么区别。

word-wrap: break-word;  内容将在边界内换行。如果需要,单词内部允许断行。

最后一个 white-space:nowrap;

当小颖给右侧的div设置的white-space:nowrap;后,div里面的内容就成了只在一行显示。
