Setting a ‘body’ to height: 100% sometimes works, sometimes doesn’t. I think the reason is that its parent, HTML, has zero height. So 100% of zero is zero. The solution: html, body {height: 100%} CSS has many unexpected characteristics. Poor design, I think. ...
而且 CSS 的值并不是一成不变的,不同的属性对应的值都会略有不同,比如:width属性,它的值可以是一个百分比的值,也可以是一个带有数值和单位;color的值可以是一个关键词,也可以是一个函数值;font-size可以是百分比、关键词,带有单位的数值;line-height可以只是一个数值,可以是百分比值,还可以是带有单位的数值...
