Setting a global percentage doesn't work, since it's basis is different. Setting a unitless value such as "1" doesn't work either. Is there some way to normalize this dimension? The computed value of line-height: normal varies between platforms, browsers (and different versions of the same browser, as you state), fonts, and even different sizes of the same font (see Eric Meyer's article) . Setting a unitless value

This is sort of tangential to coding, but programmers often do "view source" on their own pages and on others' pages.
