The font shouldn't even load unless it's needed (i.e., there's text that uses it). I *think* that's the way things work across browsers, and allows inclusion of style sheets that provide a "library" of @font-face rules that may or may not be used. That would avoid the reflow except where Ahem is actually used, which seems like the way things ought to work. -David -- 𝄞 L.
