I would like to set the size of each of the right border of my tabs contained in my menu, or force the borders to make the entire vertical length of the menu.

Here is my current code:
<http://jsfiddle.net/5FP8R/>

```
<div id="menu">
    <ul>
        <li><a class="lien_menu">
                <br>Onglet0 loooooooog</a></li>
        <li><a class="lien_menu">
                <br>Onglet1</a></li>
    </ul>
</div>

```

Thanks in advance.
