gnucash/doc/gtk-3.0.css

/* This is an example GTK CSS file that can be used with Gnucash.
   Simply copy this file to the loaction specified below according
   to your platform and then restart gnucash.

  - Windows: CSIDL_APPDATA/GnuCash
    (or the default is users\%USERNAME%\AppData\Roaming\GnuCash)

  - OS X: $HOME/Application Support/GnuCash

  - Linux: $XDG_CONFIG_HOME/gnucash
    (or the default is $HOME/.config/gnucash)

  These settings are mainly to do with register colors and can be seen
  when the preference setting 'Register\Use GnuCash built-in color theme'
  is unset.

  Note: Widgets obtained from Glade files will not be addressable
  directly by name as these are not brought in when loaded, only
  the widget type can be configured unless they are named in code.
