ol (ordered list) is parent and li (list item) is child.

Your question is wrong I think. You should ask what is the difference between ol and ul.

So ol is ordered list and ul is unordered list.

In case of ol, list will look like this

<ol>
<li>A</li>
<li>B</li>
<li>C</li>
</ol>

1. A
2. B
3. C

And in case of ul, list will look like

<ul>
<li>A</li>
<li>B</li>
<li>C</li>
</ul>

• A
• B
• C
