CSS Code to Make Header Normal (default settings) But on One Page Only?

I have used the Edit Header option to change the global settings for the Header to "Fixed Position" and the Fixed Header Style to "Scroll Back." 

These settings work great, currently, for all of my pages except for one important page where I need the header to go back to normal: where it scrolls out of frame as the user scrolls down (is not fixed) and where the header remains solid while the scroll happens (no scroll back animation).

Is there a custom code that I can use in the Advanced settings of that specific page to make the header go back to normal? 

Yes. We can do this. But you can share link to this page? We can check/give code easier
