;;; Commentary:

;; Since CSS can't be executed, this file exists solely for tangling
;; CSS from Org files.

;;; Code:

(require 'org-load)
(org-assert-version)

(require 'ob)

(defvar org-babel-default-header-args:css '())

(defun org-babel-execute:css (body _params)
  "Execute a block of CSS code.
This function is called by `org-babel-execute-src-block'."
  body)

(defun org-babel-prep-session:css (_session _params)
  "Return an error if the :session header argument is set.
CSS does not support sessions."
  (error "CSS sessions are nonsensical"))

(provide 'ob-css)
