[Solved] How can I hide forum categories from guests like this?

Code:

        $(function() {
        if (document.getElementById('logout') == null) {
        var sCategory = 'POSITION OF THE CATEGORY';
        $('.main-content:eq(' + sCategory + ')').addClass('hanckiprotected');
        }
        });

Code:

        .hanckiprotected:after {
              background: none repeat scroll 0px 0px rgba(255, 255, 255, 0.7);
              bottom: 0px;
              content: "Members Only";
              font-size: 30px;
              left: 0px;
              line-height: 310px;
              position: absolute;
              right: 0px;
              text-align: center;
              top: 0px;
              z-index: 10;
        }
        .hanckiprotected {
              position: relative;
        }
