How do I know if the code is written in HTML5 defaults? [closed]

-1

How could I apply, besides applying the knowledge I learned and the information from the available documentation, a check to see if old code written in a previous html version was updated correctly or is still using obsolete elements and / or attributes of versions of HTML5? Thank you.
