<p><strong>HTML Code</strong></p>

<pre><code>&lt;div id="item_container"&gt;
    &lt;div class="item" id="i1"&gt;               
        &lt;label class="title"&gt;T-Shirt 1&lt;/label&gt;
        &lt;label class="price"&gt;$ 20&lt;/label&gt;
    &lt;/div&gt;
    &lt;div class="item" id="i2"&gt;
        &lt;label class="title"&gt;T-Shirt 2&lt;/label&gt;
        &lt;label class="price"&gt;$ 24&lt;/label&gt;
    &lt;/div&gt;
    &lt;div class="clear"&gt;&lt;/div&gt;
&lt;/div&gt;

&lt;div id="cart_container"&gt;
    &lt;div id="cart_toolbar"&gt;
        &lt;div id="cart_items" class="back"&gt;
        &lt;/div&gt;

&lt;/div&gt;
</code></pre>
