How can I switch divs to show content using CSS

So, I have a div that needs to expand to show the list when switching. Before and after the state can be seen here http://reversl.net/box/ , but what do I need to add to my style for this to happen? I would like to use css transitions for an extra effect. I'm not worried about browser compatibility because it is just for educational purposes. Any tips?

<div class="box"><img src="http://www.placehold.it/250x300" alt="" />
        <div class="section progress">
            <h4>
                <a href="#">Div Before</a>
            </h4>
            <div class="metrics">
                <div class="meter">
                    <span style="width: 75%"></span>
                </div><!--.meter-->
            </div><!--.metrics-->

I’m afraid that I couldn’t work out in your sample code and image what you wanted to click and what you wanted to show. However, the following works with an onclick-like event with pure CSS:

<div id="wrapper">
    <ul id="top">
        <li><a href="#one">One</a></li>
        <li><a href="#two">Two</a></li>
    </ul>
    <div class="box" id="one">
        <p>One</p>
        <span><a href="#top">Close</a></span>
    </div>
    <div class="box" id="two">
        <p>Two</p>
        <span><a href="#top">Close</a></span>
    </div>
</div>

CSS

.box {
    position: absolute;
    top: 20%;
    left: 50%;
    width: 50%;
    margin-left: -25%;
    border: 4px solid #000;
    background-color: #f90;
    /* the CSS, above, is all for aesthetic purposes, what matters is the following */
    opacity: 0;
    -webkit-transition: all 1s linear;
    -ms-transition: all 1s linear;
    -moz-transition: all 1s linear;
    -0-transition: all 1s linear;
    transition: all 1s linear;
}

.box:target {
    opacity: 1;
    -webkit-transition: all 1s linear;
    -ms-transition: all 1s linear;
    -moz-transition: all 1s linear;
    -0-transition: all 1s linear;
    transition: all 1s linear;
}
