angularjs modal size

angular如果打开一个modal时需要修改窗口的大小，需进行以下设置：
$scope.NewJobModal=function(){
   var modalInstance = $modal.open({
       templateUrl:'views/modals/NewJobModal.html',
       controller:'NewJobModalInstanceCtrl',
       windowClass:'large-Modal',
          resolve:{
              p:function(){return $scope.p;}
       }
   });
};

css设置
.large-Modal.modal-dialog{
width:30%;}
