If you want to lint two or more different languages, you can combine `customSyntax` with the [`overrides`](./configure.md#overrides) configuration property.

Using the Node.js API, the `customSyntax` option can also accept a [Syntax object](https://postcss.org/docs/how-to-write-custom-syntax#syntax) or a function with those properties. Stylelint treats the `parse` property as a required value. Also, Stylelint supports syntax modules written in ESM.
