I know web design layout is different than print so what are good standards to use for column padding and line height? How much larger should header 1 be than header 2?
That's really a design issue. You can see just what the defaults are in Firefox by looking into the default C:\Program%20Files\Mozilla%20Firefox\res\html.css . You may have to change the addy a bit to match your installation. The usual default leading is 1.2, which is fine for the headers, but a bit larger would be better for regular text, imo. cheers, gary
It's all subjective and depending on the designer's taste. Some people like their designs really tight and others like them to have a lot of empty space. I usually set my h1, h2, and h3 to 1.4em, 1.2em and 1.1em, respectively.
