          I like lists. Let’s add one:

          <li>This is a bullet list.</li>
          <li>And it has three list items.</li>
          <li>Here is the third one.</li>
        </ul>
        <p>
          Do you want to see one more? I bet! Here is another one:
        </p>
        <ol>
          <li>That’s a different list, actually it’s an ordered list.</li>
          <li>It also has three list items.</li>
          <li>And all of them are numbered.</li>

          Lists would be nothing without list items.
