In my JetBrains IDEs (WebStorm, InteliJ, PyCharm, etc.) Jekyll front matter in CSS and SCSS and other files are marked as errors.
PyCharm also marks numerous other legal Jekyll constructs (
@import using file name only, Liquid variables, etc.) as errors or warnings; so help with those would be appreciated too.
How do I configure my IDEs (PyCharm will do) so that I can develop a Jekyll site without spurious errors?
