This step is focused on the importance of HTML formatting for a better look and feel.
Every child tag should be indented inside of its parent tag to improve readability, like this:
<ul>
<li> Child Element 1 </li>
<li> Child Element 2 </li>
</ul>
So this lesson is actually asking you to do the exact same for the h2 , comment and p elements nested inside the main element. You’re supposed to indent the child elements with whitespace.
please what does this mean: Your h2 element should be below the main element’s opening tag and its opening tag should start 6 spaces over from the start of the line.
