You can then target that selector in your CSS.\n     * @param {string} options.id The string to use as the `id` for the step.\n     * @param {number} options.modalOverlayOpeningPadding An amount of padding to add around the modal overlay opening\n     * @param {number} options.modalOverlayOpeningRadius An amount of border radius to add around the modal overlay opening\n     * @param {object} options.popperOptions Extra options to pass to Popper\n     * @param {boolean|Object} options.scrollTo Should the element be scrolled to when this step is shown? If true, uses the default `scrollIntoView`,\n     * if an object, passes that object as the params to `scrollIntoView` i.e. `{behavior: 'smooth', block: 'center'}`\n     * @param {function} options.scrollToHandler A function that lets you override the default scrollTo behavior and\n     * define a custom action to do the scrolling, and possibly other logic.\n     * @param {function} options.showOn A function that, when it returns `true`, will show the step.\n     * If it returns false, the step will be skipped.\n     * @param {string} options.text The text in the body of the step. It can be one of three types:\n     * ```\n     * - HTML string\n     * - `HTMLElement` object\n     * - `Function` to be executed when the step is built. It must return one the two options above.\n     * ```\n     * @param {string} options.title The step's title. It becomes an `h3` at the top of the step. It can be one of two types:\n     * ```\n     * - HTML string\n     * - `Function` to be executed when the step is built. It must return HTML string.\n     * ```\n     * @param {object} options.when You can define `show`, `hide`, etc events inside `when`. For example:\n     * ```js\n     * when: {\n     *   show: function() {\n     *     window.scrollTo(0, 0);\n     *   }\n     * }\n     * ```\n     * @return {Step} The newly created Step instance\n     */\n    function Step(tour, options) {\n      var _this11;\n      _classCallCheck(this, Step);\n      if (options === void 0) {\n        options = {};\n      }\n      _this11 = _super9.call(this, tour, options);\n      _this11.tour = tour;\n      _this11.classPrefix = _this11.tour.options ? normalizePrefix(_this11.tour.options.classPrefix) : '';\n      _this11.styles = tour.styles;\n      /**\n       * Resolved attachTo options.
