# Skin-specific notes:

|

# - Fonts are not loaded due to CSP. One possible mitigation is running a
|
||||
# local proxy and setting `Access-Control-Allow-Origin` to `*`. An example
|
||||
# nginx configuration:
|
||||
#
|
||||
# server {
|
||||
# listen 127.155.44.48:80;
|
||||
# server_name 127.155.44.48; # This address was chosen randomly
|
||||
# location / {
|
||||
# proxy_pass https://wiki.c2dl.info; # Replace with your wiki
|
||||
# add_header Access-Control-Allow-Origin *;
|
||||
# }
|
||||
# }
|
||||
#
|
||||
# By modifying `/etc/hosts` this can be made into its own "domain":
|
||||
#
|
||||
# 127.155.44.48 local.wiki.c2dl.info
|
||||
#
|
||||
# - The module `skins.citizen.scripts.toc` is broken because to find and
|
||||
# highlight the current section header in the table of contents it uses a
|
||||
# CSS selector incompatible with the URL rewriting applied to anchor links.
|
||||
#
|
||||
# - The module `skins.citizen.scripts` references search inputs which aren't
|
||||
# created by this script.
