  "Generates an HTML footer with Bootstrap classes.

TEXTBODY: Specifies the color scheme of the text body, default is 'secondary'.

SPACING: A list specifying the Bootstrap spacing class. The list should contain
keyword arguments that can be passed to the cl-sbt-spacing:spacing function.

BODY: Optional. Specifies additional HTML content to be added to the footer.
This can be any valid HTML content that spinneret:with-html can parse.

The footer generated contains fixed content, including a 'Back to top' link and
a short paragraph about Bootstrap.

Example usage:
  (footer (:textbody \"primary\" :spacing (:property :p :side :y :size 4))
          (:p :class \"custom-class\" \"Custom content here\"))
  ; This will generate a footer with primary color text and a top/bottom
  ; padding of size 4. Additionally, a paragraph with class 'custom-class'
  ; and text 'Custom content here' will be added to the footer."
