Here’s something peculiar I came across recently:

On the left is what I saw in Chrome and on the right is what I saw in Chrome after I’d deleted ‘Gotham-Light’ from the beginning of that page’s <body> font stack within the Chrome Web Inspector. Actually, there were a couple of linked CSS files on this page competing for control over which font the browser should use to display text. Here’s what I saw:
body {
color: #999999;
font-family: 'Gotham-Light', Helvetica, Verdana, sans-serif;
font-size: 10pt;
}
followed by:
body {
font: 13px/1.231 arial,helvetica,clean,sans-serif;
}
Now, I won’t even comment on what’s wrong with that second body style—just don’t meditate on it too long or your brain will come pouring out your nose.
The first one, however, I will go off on. First, who would think that a good fall-back font for Helvetica is Verdana but someone who couldn’t tell the two apart? I submit that such a person should not be specifying typefaces—anywhere. Second, if you’re going to use standard OS fonts (meaning you’re not using a webfont technology like TypeKit, FontDeck or the Google Font API), why not ensure that everyone is seeing the same one by specifying a good ol’ Core Font for the Web first such as Verdana, Arial, Georgia, etc? These come installed on both Mac and Win PCs by default, right? Well, I’ll tell you which font doesn’t come installed by default on any PC running any OS: Gotham-Light.
I happen to be one of the random individuals this web developer was fishing for when he/she specified Gotham-Light as the primary font-family for this website. The particular version I have installed on my Win 7 PC is an old postscript font I purchased eons ago from Hoefler Frere-Jones (along with a few other of their exquisitely designed typefaces) back when I was an active print designer. The Gotham family is permanently activated as I often find use for it when no other sans-serif font seems to do the trick.
In any case, the font’s postscript code used to create the character shapes and spacing was never intended for entirely accurate (much less beautiful) representation on computer displays and the screenshot on the left shows why. Actually, on my Win 7 PC, only Chrome and Safari displayed the text in Gotham-Light, albeit poorly. IE 9 and Firefox 4 simply ignored it.
Mind you, this is no amature amateur website. It is for a major consumer brand with an extensive online presence. We’ve all got dirty laundry, I guess. But, I come across font-failures like this one fairly often and I just have to question the initial logic that created them.
And there I went.
