Subject Re: YUI compressor for CSS (relates to apache/royale-compiler#39)
Date Mon, 09 Apr 2018 18:57:00 GMT
Woah. Did I read that right?

Anyone who uses Jewel will automatically have a 31k of CSS before any app specific css? That’s
a lot of CSS which might or might not be used. My current app has a total of 13KB *including*
my custom css.
