+# NixOS FontSize
+
+NixOS/Wayland can cause a bug where the `font-size` css property does affect the rendered page. To fix this add the following to your devShell.
+
+```shell
+    shellHook = with pkgs; ''
+      export XDG_DATA_DIRS=${gsettings-desktop-schemas}/share/gsettings-schemas/${gsettings-desktop-schemas.name}:${gtk3}/share/gsettings-schemas/${gtk3.name}:$XDG_DATA_DIRS;
+      export GIO_MODULE_DIR="${pkgs.glib-networking}/lib/gio/modules/";
+    '';
+```
