 * Add a stylesheet rule to the document (it may be better practice
 * to dynamically change classes, so style information can be kept in
 * genuine stylesheets and avoid adding extra elements to the DOM).
 * Note that an array is needed for declarations and rules since ECMAScript does
 * not guarantee a predictable object iteration order, and since CSS is
 * order-dependent.
 * @param {Array} rules Accepts an array of JSON-encoded declarations
 * @example
