In the future, you'll be able to use the overrides configuration property. In the meantime, you can work around this missing feature by using the extend configuration property and by running stylelint twice.
Create a second config that extends the more limited main config and turns on additional rules:
.extended-stylelintrc.json:
{
extends: "./.stylelintrc.json",
rules: {
"unit-whitelist": ["px"]
}
};
Or you can create a second config that extends a full main config and turns off rules:
.limited-stylelintrc.json:
{
extends: "./.stylelintrc.json",
rules: {
"property-no-unknown": null
}
};
It will require two npm tasks to run it, though:
stylelint "**/*.css"
stylelint "special/**/*.css" --config .extended-stylelintrc.js
Or it can be combined into one:
stylelint "**/*.css" && stylelint "special/**/*.css" --config .extended-stylelintrc.js
