[Ur] Stylesheet questions

[Edward Z. Yang]

Hello Byrn,

Ur currently doesn't have very much support for serving resources
like CSS; so the onus is on you to run another webserver which hosts
your static resources and then setup <link> to point to the URL (make
sure you allow the URL in the urp.)

I'm not 100% sure if this is ultimately a good solution, but you use
'url (blogStyle ())' to get a URL which is valid for href.

Cheers,
