Mailchimp Sign Up Form Header and Footer, Change Colour of Floating Top Button

My website: pembrokeroadassociation.ie

I have three queries.

  1. I would like to change the CTA (Call to Action) button on the header image on my static homepage, so that a mailchimp email sign up form appears instead. Is this possible?

  2. Can I change the colour of the ‘return to top’ floating arrow button?

  3. Can I add a mailchimp email sign up form centered, to the footer? I would like the submit button to be an envelop if possible. And to change colour when hovered on.

Thank you
