You can use this filter to selectively serve something else to browsers which don't support TTF/OTF/WOFF embedding through @font-face.
- Safari
- Chrome¹
- Opera
- Gecko-based browsers
- Konqueror²
- SVG format [planned]
Internet Explorer supports @font-face since version 4.
Still if you wanna target a specific version of IE you could use downlevel-revealed conditional comments and add ||(!+"\v1") to the filter.
Reminder: ids can potentially pollute the global scope so remember to avoid naming them chrome, opera or konqueror.
¹ except 4.0.249.2–11
