Thankyou so so much for this! I actually realised I had sent you the wrong codepen hahahaha but I followed this layout and it worked (sort of)
So its displaying on my website now, as you can see here https://www.ignatiabelle.com/, but its affecting the whole site rather than just sitting as a header at the top.. is there a way I can fix this? as the whole site isn't functional now.
This is the code I put in a code block
