1.  子元素会继承父元素已计算的行高，而不是百分比

参考：https://www.w3.org/TR/2008/REC-CSS1-20080411/

Often, the value of a property is a percentage that refers to another property:

P { font-size: 10pt }
P { line-height: 120% }  /* relative to ‘font-size‘, i.e. 12pt */

For each property that allows percentage values, it is defined what property it refers to. Children elements of ‘P‘ will inherit the computed value of ‘line-height‘ (i.e. 12pt), not the percentage.
