 Waybar uses Cascading Style Sheets (CSS) to configure its appearance.
 
-It uses the first file found in this search order:
+When the system appearance is light, Waybar first looks for *style-light.css*.
+When the system appearance is dark, Waybar first looks for *style-dark.css*.
+If no appearance-specific stylesheet is found, it falls back to *style.css*.
 
-- *$XDG_CONFIG_HOME/waybar/style.css*
+Waybar uses the first file found in this search order for each stylesheet name:
-- *~/.config/waybar/style.css*
+
-- *~/waybar/style.css*
+- *$XDG_CONFIG_HOME/waybar/<stylesheet>*
-- */etc/xdg/waybar/style.css*

+- *~/waybar/<stylesheet>*
