Basis for CSS optimization. Start by trying to analyzing a CSS file.

• count CSS selectors
• count CSS properties, especially most frequent properties
• filter CSS properties
• order CSS properties ala CSS Comb
• explore phloc-css; more complicated than desired

• explore OBSP CSS Parser
  • learned how to import dependencies from GitHub projects
  • jUnit tests in src/test/groovy/com/github/itgumby/OsbcpParseTest
  • simple, clean interface
  • unsuitable for media queries
• explore CssParser (implementation of SAC)
  • jUnit tests in src/test/groovy/com/github/itgumby/ParseCssTest.groovy
  • example in src/main/groovy/com/github/itgumby/analyzeCss/ParseExample.groovy
  • both based on code gleaned from StackOverflow
  • unsuitable for @media media selectors
• explore W3C SAC
  • unsuitable SAC has no implementation, just an interface
