stylelint: errors by collapsing multi-line selectors in CSS

Open on Drupal.org →
Created on 27 August 2025, 22 days ago

Problem/Motivation

Running stylelint reports 9 prettier/prettier errors caused by multi-line CSS selector lists in the Calendar module’s styles. This creates CI noise/failures.

Proposed resolution

  • Reformat offending selectors to single lines per Prettier’s expected output (no line breaks between simple selectors).
  • Apply automated formatting:
    $ core/node_modules/.bin/prettier --write "web/modules/**/calendar/css/**/*.css"

    (or manually edit the noted lines to single-line selectors).

  • Re-run stylelint to verify zero errors.
