>How did you calculate 100% = 1em ? That's the definition in the spec. "On the 'font-size' property, [ems] refer to the computed font size of the parent element."
So 1em equals the font-size of the parent element. And "[percentages] refer to inherited font-size." The inherited font size of an element is the font-size of the parent element. So 100% equals the font-size of the parent element. Therefore, 1em = 100% = the font-size of the parent element. ---Tim ______________________________________________________________________ css-discuss [css-d@lists.css-discuss.org] http://www.css-discuss.org/mailman/listinfo/css-d List wiki/FAQ -- http://css-discuss.incutio.com/ List policies -- http://css-discuss.org/policies.html Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
