Hi @Cristian3000 , welcome to the forum.
The task is asking you to add 2 spaces before the opening tag of any element nested inside the main element (the children of the main element).
This will create an “indented” structure where the code of the children is pushed more to the right than their parent.
This indentation helps with the readability of the code, because you can clearly see where an element starts and where it ends.
An example of indented code could be the following. Notice that the opening tags don’t start all at the position:

<html>
  <head>
    <title>Title for the page</title>
  </head>
  <body>
    <h1>Big title</h1>
    <p>Paragraph</p>
  </body>
</html>
