I have never seen that value for font size before. However, if you wish to have it at that size, you can put 1.5em, rather than the math function you have. I'm guessing you are trying to get the value of 2.2/1.5 as the font size, which equals to 1.4666, round that up and you get 1.5, which is a better syntax.
it's not math, it's declaring font-size as well as line-height (which is valid without specifying a unit of measure).
I don't think it's valid, as the font-family is missing. ie., this is valid: font: 2.2em/1.5 sans-serif; ****************************************************** The discussion list for http://webstandardsgroup.org/ See http://webstandardsgroup.org/mail/guidelines.cfm for some hints on posting to the list & getting help ******************************************************
