Missing.css 1.1.0

• Added npm exports for more convenient importing:

  Import	Used to be
  missing.css	missing.css/dist/missing.min.css
  missing.css/prism	missing.css/dist/missing-prism.min.css
  missing.css/js/*.js	missing.css/dist/missing-js/*.js

• Dialogs have better contrast.

§ For developers

• In this release, we switched from PostCSS to Lightning CSS.

• With the introduction of CSS nesting in ~all browsers, Missing.css can now be run directly from source! This is how this website itself uses it -- check the devtools style editor to see it in action. We still transpile for wider browser support.
