Need help removing header and footer from one Squarespace page

I am experiencing while trying to remove the header and footer from one specific page on my Squarespace website.

I have attempted to do this using a custom CSS code, but unfortunately, it doesn't seem to be working as expected. I have followed the instructions provided in the Squarespace knowledge base, but I am still encountering difficulties.

From your screenshot I can see that the css has some syntax errors. Could you please share the website and I can guide you through it. 

Hey @emi3033, looks like you're missing a closing curly bracket, add one in at the end and the code should work.
