Hi you,
#3. Header:
As I said above, we don’t use elementor’s header +footer builder to create headers and footers for the website.
I reinstalled the header + footer for you, however I see you turned it off and used elementor’s header + footer builder.
– The use of header + footer must go together, ie if you use footer builder, you must use both header builder for the website.
– I will not interfere with your customization, however we will not support if you continue to use header + footer builder
#6,7,8. I just added some color CSS customizations for you, please check again
