- A: 
- - (defun flat-style(theme &rest args)
- -   (custom-set-faces
- -    `(mode-line
- -      ((t (:inherit mode-line
- -                    :box (:line-width ,mode-line-height :style
- flat-button)))) t)
- -    `(mode-line-inactive
- -      ((t (:inherit mode-line-inactive
- -                    :box (:line-width ,mode-line-height :style
- flat-button)))) t)))

+ CHANGES IN EMACS MASTER make the code above CRASH. Emacs,
+ The new flat-style function uses set-face-attribute:
+ ```
+ (defvar mode-line-height 8 "Size of the box arounf the mode line")
+
+ (defun lat-style (theme &rest _)
+ (set-face-attribute 'mode-line nil
+ :box (list :line-width mode-line-height :style 'flat-button))
+ (set-face-attribute 'mode-line-inactive nil
+ :box (list :line-width mode-line-height :style 'flat-button)))
+ ```
+
- Q: Do you teach Emacs to any of your university students?
- A: No teaching, but a lot of introdcuing ;-)
