JQuery switch with cookies: how to get default minimized state and stay available?

I am a complete newbie, so excuse my inability to see the obvious solution (if any). However, I checked interweb for the answer to this question and ran into the same question. So far I have worked: using what I found at http://www.tobypitman.com/multiple-collapsable-panels-with-cookies/ , I managed to get some containers to switch between display:blockand display:none, and I set cookies with using the Klaus Hartl cookie.js.

Everything works horribly! Except that I want the initial state of the switch containers to be closed. I really would like to do this without having it display:nonedirectly in CSS, so the content remains available with JS disabled. I am not a programmer, and my brute force method of changing things here and there until something happens does not completely cut it. I have included HTML, CSS and jQuery all the below - the only thing that will not be in my example is a sprite with a CSS image for <h6>, which serves as a trigger.





    
    Toggle with cookie
<style>
    .toggle-wrapper {
        overflow:hidden;
        display:block;
    }

    .toggle-wrapper .toggle-container {
        position:relative;
        overflow: hidden;
    }

    .toggle-wrapper h6.trigger {
        background: transparent url(images/trigger-sprite.png) no-repeat left top;/*sprite is 15x30px - plus sign on top, minus on bottom*/
        height: 15px;/*half of sprite height*/
        cursor:pointer;
        padding:0 0 0 16px;
        margin:0;
    }

    .toggle-wrapper h6.active {
        background-position: left bottom;/*this is the open state, showing the minus sign part of sprite*/
        padding:0 0 0 16px;
    }
</style>
