Description

Description

See https://github.com/WordPress/gutenberg/issues/61241

Some components come with CSS in JS.

https://github.com/WordPress/gutenberg/issues/61241 and https://github.com/WordPress/gutenberg/pull/61243 aim to introduce a stylelint rule to prevent usage of the order CSS property, which is impactful for accessibility.

In the same way, it would be nice to add an ESLint rule to prevent usage of the order CSS property in any *.js file.

Unfortunately this isn't exactly my area of expertise so that I'd appreciate some guidance. I did see a similar rule added in https://github.com/WordPress/gutenberg/pull/58130

Step-by-step reproduction instructions

  • Add an order CSS property e.g. order: 1; to any CSS-in-JS for example in this file..
  • Run npm run lint:js.
  • Observe the linter does not report any error.

Research direction
Refer to the existing ESLint rule added in PR #58130 for implementation pattern. The rule should detect CSS 'order' property in CSS in JS strings. Test with files like packages/components/src/palette edit/styles.ts. Consider consulting the related stylelint rule issue #61241 for context.
