I don't know how much deeper it goes, but it does have some context:

  Prompt: Given this html, what does an end user see?
  <div style="display:none">hello</div><div>you</div>

  ChatGPT:
  An end user would see only the text "you" on the webpage.

  The first <div> element has the inline style display:none, which means it is set to be hidden, and its content "hello" will not be visible to the user. On the other hand, the second <div> element has no specific display style, so it will be visible, and its content "you" will be displayed on the webpage.
