// CSS styles for coverage.py HTML reports.

// When you edit this file, you need to run "make css" to get the CSS file
// generated, and then check in both the .scss and the .css files.

// When working on the file, this command is useful:
//      sass --watch --style=compact --sourcemap=none --no-cache coverage/htmlfiles/style.scss:htmlcov/style.css
//
// OR you can process sass purely in python with `pip install pysass`, then:
//      pysassc --style=compact coverage/htmlfiles/style.scss coverage/htmlfiles/style.css

// Ignore this comment, it's for the CSS output file:
/* Don't edit this .css file. Edit the .scss file instead! */
