I wanted to customize org-meta-line to make the source code headers look smaller, I'm using this line:
(set-face-attribute 'org-meta-line nil :height 0.5 :slant 'normal :foreground "#C0C0C0" )
as mentioned here
it looks like this:
but I get this error when my init.el is being loaded:
Warning (initialization): An error occurred while loading ‘/home/kronolynx/.emacs.d/init.el’: error: Invalid face, org-meta-line
How can I fix the error?
