Is it possible in javaScript when you have a font list on a website, for javaScript to write a rule so that if the first font is not available in a browser, the second font on the list can have a different size to the first?
Was expecting to build the site with the body text to be 100% and other text in relative ems, but want 1st font (arial narrow) and second font (arial) to take up the same amount of space if its replaced and dont know how to do it.
any ideas? thanks
