h1 {

A different thing is if you set a margin in percentage or ems; here a percentage means a percentage of the screen size while a margin in "ems" means a margin based on the font-size you are using in the respective style.

Yeah, I have no idea why I developed the style sheet the way I did, except that it "looks good to me" in every reader and app I have been able to try. "Looks good to me" is the iron rule that guides my life.
