<!--HTML...the children divs of ".main" can have their own unique classes if that helps-->
<div class="main">
    <div></div>

CSS

/*CSS-some of this creates other events not mentioned above. These are simplified versions of what I need for my final site design*/

.main  {
    width: 450px;
}
.main div {
    height: 100px;
    width: 100px;
    background-color: #000;
    margin: 3px;
    float:left;
}
div.select   {
    background-color: #f00;
    border: 2px solid #00F;
    margin: 3px;
    float:left;
    display: block;
}
div.active   {
    background-color: #f00;
    margin: 3px;
    float:left;
    display: block;
}
hr  {
    background-color: #FF0;
    float: left;
    display: block;
    height: 20px;
    width: 450px;
}
hr.open {
    float: left;
    display: block;
    height: 300px;
    width: 450px;
}

JavaScript

/*the JS - sorry about the double quotes.  I'm using Dreamweaver, which seems to add them to everything*/

$(document).ready(function() {
//dynamcally adds the <hr> after every 4th div.
    $(".main div:nth-child(4n)").after('<hr class="closed"></hr>');
//puts a blue border on the squares
    $('.main div').hover(function()  {
        $(this).addClass('select');
    },
    function() {
        $(this).removeClass('select')
    });
//changes the color of the active square to red and "deactivates" the previous one.
    $('.main div').click(function()  {
        $(this).toggleClass('active').siblings().removeClass('active');
        $('hr').removeClass('open', 1000);
        $(this).nextAll("hr").first().addClass('open', 500);
    });
});
