[Theme: Oxygen] Remove Header, Menu, Footer from Static Front Page

Does anyone have any knowledge of the CSS code to remove header, menu, page title, and footer from the front page in the Oxygen theme?

I have looked at other topics related to this but can’t seem to translate it on the site. I can navigate my way to the Custom CSS editor and style sheets but am not sure what to do from there.

Any help is appreciated!
