Hi,
Can you share your site URL?

Thanks!

Thanks for sharing!
I found the spacing comes from the theme.
You can use the custom CSS code below to Customizer -> Additional CSS

body #primary {
    margin: 0;
}

Hope it helps!

Thank you for your response! It worked perfectly now

You’re welcome.
Have a nice weekend!

Update: it works now on the desktop. but there is still blank space on mobile

You can use this code

@media (max-width: 768px){
   #primary, #secondary {
       padding: 0;
   } 
}

All good now! Many thanks once again
