I know that we can customize org source block begin and end line colors using below config
(custom-set-faces! ;; Customize the header line of the source block '(org-block-begin-line :background "#1a1e26" :extend t) ;; Customize the footer line of the source block '(org-block-end-line :background "#1a1e26" :extend t) ) But is it possible to have different color based on language or any other properties?
font-lock. BTW, all of this is off the top of my head: I haven't tested anything.
