ESLint has broadened its linting capabilities to include CSS, aiming to alleviate common debugging challenges developers face, particularly with CSS cascade issues. This update complements existing support for JSON and Markdown. Key features include built-in linting rules for CSS, such as checks for duplicate at-imports, invalid properties, and a crucial require-baseline rule that enables developers to check CSS features based on their support across different browsers. This initiative is part of the W3C's Baseline effort, promoting consistency and predictability in CSS styling across major browsers, ultimately enhancing the developer experience.
The ESLint team has officially announced support for CSS, allowing developers to enforce CSS rules and reduce debugging time spent on cascade-specific issues.
CSS linting will help developers specify which CSS features to check, taking into account their maturity across core browsers, improving compatibility.
