Does font stack probability depend stack order?
Yes, one point that may not be obvious about the font stack builder (though it is explained) is that the probability that fonts down the stack are displayed is calculated from the remainder of those above. For example, Arial is available on about 97% of Macs, Helvetica is available on 100%. If you put Arial above Helvetica, the probability that Helvetica is displayed on a Mac is about 3%. If you move Helvetica above Arial, no Mac users see Arial. To take a contrived example, if the first font has 80% frequency, that leaves a 20% probability that any other font is displayed. If the second font in the stack has 20% frequency, that equates to a fifth of the remaining 20% which equals 4%. That leaves 16% fall-through to the next font in line. If no further fallback font is named, an un-specified font that belongs to the generic font-family should be displayed, as shown on the bottom line of the font stack table. In CSS there is no disadvantage in giving a long list of fallback fonts. The p
