I'm having a problem implementing OpenType features in web fonts. No matter what typeface or browser I use—and I've tried several of each—I can't get the CSS font-face property to listen to font-variant:small-caps. In every case, the browser synthesizes its own small caps by scaling the full caps, which of course looks terrible.
The typefaces I've tried with this are all open-source advanced fonts: Cabin, Cardo, Lato, and Sorts Mill Goudy, all of which support small caps at least in their roman, regular-weight face. I've used Firefox 5, Opera 11.5, and the latest build of Iron (Chrome without Big Brother), all to no avail.
It's worth mentioning that other properties of advanced web typography, such as automatic ligatures (as well as the font-face property itself), are all working.
Yeah, that doesn't work.
CSS 3 supports directly accessing real small caps. Currently only Firefox supports this, and only via moz-prefixed properties (which makes sense as CSS 3 isn't final yet).
I've read that, and I tried the Mozilla-only workaround, thinking it would be nice if it worked in at least one browser. But the workaround never loaded any small caps at all. I've updated the test page to reflect that problem—look at the entries 2.1, 4.1, and 6.1: http://www.utcolmus.org/test.html
