1、当line-height:XX%时:
body{font-size:14px;line-height:150%;}
p{font-size:26px;}
结果就是:
body{line-height:21px;}//14*150%=21
p{line-heigt:21px;}//继承父元素

2、当line-height:X.X时:
body{font-size:14px;line-height:1.5;}
p{font-size:26px;}
结果就是:
body{line-height:21px;}//14*1.5=21
p{line-height:39px;}//26*1.5=39
