规范如此,就是这么任性https://www.w3.org/TR/REC-html40/struct/text.html#h-9.1
如果不自动压缩空格,那我们写html的时候就只能写成1行了,否则先这样的代码就会出现大段的空白。
既然浏览器会压缩多个空格,那只要保证文本里每次只有一个空格相邻不就可以了。
□ -> □ □□ -> □ □□□ -> □ □ □□□□ -> □ □
自动规避了浏览器的合并空格策略。
这个思路来自于富文本编辑器,
word-wrap: 决定句尾放不下单词时,单词是否换行
word-break: 决定单词内该怎么换行
平文本可以配合white-space: pre-wrap来解决多空格压缩显示问题
富文本采用的解决方案是对空格进行间隔html转义,这种方法更灵活,可以适应不同的场景,也适用于平文本。
white-space我们更多的时候只用到nowrap的属性,来配合实现…的特效,实际它还有更多的姿势未解锁。
white-space: normal | nowrap | pre | pre-wrap | pre-line
我们重点关注pre开头的几个属性。pre是preserve(保留)的缩写。没错,它就跟保留空格有关系。
pre: 保留所有的空格和回车,且不允许折行。
pre-wrap: 保留所有的空格和回车,但是允许折行。
pre-line: 会合并空格,且允许折行
后台按照用户的输入的原始空格返回,不用做转义,前端加上
word-break: keep-all; word-wrap: break-word; white-space: pre-wrap;
CSS单词换行and断词
字符画很好玩,压缩空格就全乱了
#897
word-break: break-all, 打破了浏览器的默认换行规则
word-wrap: break-word, 保留浏览器的默认换行规则,一旦一个连续长单词一行容纳不下,就只对这个长单词进行打破换行

.container::selection { background: red; }
text-align-last: justify;
另外,这个 .nav li:first-child ~ li(不包括最后一个li) 也是不包括第一个li 而且 第一个的话 :first-child 好像是可以不用写的吧 就是 .nav li ~ li , 作者写是考虑可读性吧
