Line Height Best Practices

line-height

body{
    font-size:62.5%; /*to get base 10 and use ems or REMS more easily, biseer 1.4rem = 14px*/
    /*use REMS much easier and saves lots of calculations*/
    line-height:1.5; /*kind of standard and best-practice*/
}
h1,h2,h3,h4,h5,h6 {
    line-height:1.2;/*usually don't need as much line height space as paragraphs*/
}
sup,sub {
    line-height:0;/*always to prevent them from increasing the height of the line box*/
}
