Hooks

checkcss.onClassnameDetected = function (classname, element) {
  // Return `false` to disable checks for `classname`.
  // For example, to ignore classnames starting with
  // "license-" or "maintainer-"...
  return /^license-|^maintainer-/.test(classname) ? false : true;
};

checkcss.onUndefinedClassname = function (classname) {
  // Custom logging goes here (replaces default log method)
};
