By this step, you should have only a h2, a comment and a p element nested inside your main element, as done in the previous lesson.
This step in particular 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 the example shown in the step:
<ul>
<li> Child Element 1 </li>
<li> Child Element 2 </li>
</ul>
So this lesson is asking you to do the exact same for the h2 , comment and p elements nested inside the main element.
Well, this step is asking for you to format this code according to the usual HTML formatting guidelines that makes it easier for humans to read and understand. (You can read more about HTML formatting here)
In this step, you should have one parent element main and three child elements nested inside it:<h2>, <!----> and <p>.
Therefore, you should format the whole code snippet just like the project is showing in their example:
<ul>
<li> Child Element 1 </li>
<li> Child Element 2 </li>
</ul>
The elements are all one right below the other and the child elements are indented by two spaces.
