Remove Menu (header) and Social Links (footer) from Landing Page

Hi There

I am looking to remove the header and footer from my landing page. Adding CSS doesn’t seem to have worked for me and I don’t have the option for ‘no header/footer’ in my page attributes.

Is there a way for me to remove these? Page below:
