 That provides a few more options to fall back to if the preferred font isn't available. But let's see about making that font available.

+A previous version of this post also included the `.woff` file in addition to `.woff2`. A kind reader let me know that [basically everything](https://caniuse.com/?search=woff2) supports `.woff2`, and since `.woff2` offers much better compression than first-generation `.woff` there *really* isn't any reason to offer a font in `.woff` format in this modern age. I can just offer `.woff2` on its own.

 And that would work just fine... but it *would* require storing those web font files in the (public) [GitHub repo](https://github.com/jbowdre/runtimeterror) which powers my site, and I'd rather not store any paid font files there.
 
 So instead, I opted to try using a [Content Delivery Network (CDN)](https://en.wikipedia.org/wiki/Content_delivery_network) to host the font files. This would allow for some degree of access control, help me learn more about a web technology I hadn't played with much, and make use of a cool `cdn.*` subdomain in the process.
