You are on the right track with the list, but there are some validation errors with the markup. When using a ul or ol list _EVERYTHING_ in the list needs to be inside ````<li></li>```` tags in that list. So something like this is more what you want.


````
<ul class="QA">
    <li>
        <h3>question</h3>
        <p>answer</p>
    </li>
    <li>
        <h3>question</h3>
        <p>answer</p>
    </li>
</ul>
````
Notice there is only one set of ````<ul></ul>```` and each Question and Answer pair is in a ````<li></li>```` pair.
