Hello @ zwemanhein
The question is asking to indent two spaces in the codes inside the main part, instead of copying the example given.
This part in the question is for reference instead of copying.
<ul>
<li> Child Element 1 </li>
<li> Child Element 2 </li>
</ul>
What you need to do is something like this: (leaving previous codes unchanged and only changing the spacing)
<main>
<p></p>
</main>
Hope this helps
Happy Coding
