<ul id="ave">
    <li><a href="#ave">Ave verum</a></li>
    <li>Ave verum corpus, natum de Maria Virgine, vere passum, immolatum in cruce pro homine,</li>
    <li>cuius latus perforatum unda fluxit et sanguine: esto nobis praegustatum in mortis examine.</li>
</ul>

<div id="gaudeamus">
    <h2><a href="#gaudeamus">Gaudeamus</a></h2>
    <p>Gaudeamus igitur, Juvenes dum sumus!
    Post jucundam juventutem, Post molestam senectutem, Nos habebit humus!</p>
</div>

<div id="odi">
    <h2><a href="#odi">Odi et amo</a></h2>
    <p>Quare id faciam, fortasse requiris. Nescio, sed fieri sentio et excrucior.</p>
</div>
