Description: 

Drupal Core is transitioning to using Stylelint for CSS linting.

To install stylelint you will need yarn. Once yarn is installed, run the following command from DRUPAL_ROOT/core

yarn install

To install Drupal 8's JS dependencies, of which stylelint is one.

To run it on all core css files. Run the following command from DRUPAL_ROOT/core

yarn run lint:css

Initially, only a skeleton set of CSS rules will appear, and the process of adding more rules will continue.

Eventually contributed modules and themes will be able to leverage stylelint as well - #2876298: [12.x] Remove scaffolded csslint and eslint config

Would it be good to mention here that this not what DrupalCI is using yet. This issue is postponed: https://www.drupal.org/node/2866840

I've started a handbook page: Javascript Developer tools for Drupal core. It will gather details of the JS dev tools from this change record (and others). It still needs work, contributions welcome.
