How do you set the value in an order list?

Not with CSS, that's how!

<ol>
  <li value="3">This is item three.</li>
  <li value="50">This is item fifty.</li>
  <li value="100">This is item one hundred.</li>
</ol>

Result:

3. This is item three.
50. This is item fifty.
100. This is item one hundred.

I only I had read the HTML5 Doctor articles we were putting out at the time 🤦
