Headings: Appropriate nesting - Failed

Headers must follow the order of h1, h2, h3, h4, h5, h6 .  An h1  header must be followed by an h2 , an h2  must be followed by an h3 , and so on.

    • Adobe will highlight the element with a green box

  • In the tags panel, we see this element is an h3 .  Immediately above it is an h1 .  The element is not following the correct order and must be refactored as an h2 

    • Right-click on the h3  and go to Properties

    • An Object Properties  dialogue box will appear
