Custom Blank Page no header, logo or announcement bar

I would like to create a landing page where I can just start typing. Can someone paste the code I’d put in a new custom post so that it removes header, announcement bar, logo, etc.

Thank you

The best way to accomplish this is probably to edit the theme to make a custom template. Another option might be to write a bunch of css to hide the unwanted elements. What you need would be theme specific.
