LOL - I just looked at the HTML in AA 2.7, and found the JS and CSS tags in the <body>. Only one <head> though.

It works correctly if you put the super at the end instead of the beginning:

module AdminPageLayoutOverride
  def build(*args)
    # This will be added at the beginning of <head>
    within head do
      # stuff here
    end

    # This will be added at the beginning of <body>
    # within body do

    # end

    super
  end
end
ActiveAdmin::Views::Pages::Base.prepend(AdminPageLayoutOverride)

That being said, I think the recommended way to do this now is via the # Register Stylesheets & Javascripts section of the active_admin.rb initializer.

If you don't have that section (I didn't), then assuming your codebase is in a repo, you can rerun the AA generator to get the updated initializer, skipping everything you can except the initializer generation, reverting everything except the initializer changes, and then using the diff to decide what to revert in the initializer. (There may be a better procedure than that, but that does work.)

Note that the above didn't work for me on AA 2.7, but this comment did: activeadmin/activeadmin#5201 (comment)

Thanks. I was finally able to change AA color, even though we're using the same build to deploy to multiple environments

def build_active_admin_head
    within super do
      text_node("<style>:root {--primary-color: #{Rails.env.production? ? '#ff8b41' : '#505050'};}</style>".html_safe)
    end
end
