What Is The Code For This Navigation Alternative?

Site URL: https://www.creativejam.in/

Hello Friends,

I've come across this website today, realized that it's built in Squarespace, and wondered how I could use a similar navigation system on my own website, ozankarakoc.com.

I managed to use the hamburger icon and the overlay menu thanks to the amazingly helpful people here in this forum, but I wonder how I could;

• adjust the size of the overlay,
• align it to a side,
• change the font properties of the text,
• add additional text below the menu items,
• and social media links.

Any help would be highly appreciated 😉

Thank you!
Ozan
