+# NAME
+
+waybar - backlight slider module
+
+# DESCRIPTION
+
+The *backlight slider* module displays and controls the current brightness of the default or preferred device.
+
+The brightness can be controlled by dragging the slider across the bar or clicking on a specific position.
+
+# CONFIGURATION
+
+*min*: ++
+    typeof: int ++
+    default: 0 ++
+    The minimum volume value the slider should display and set.
+
+*max*: ++
+    typeof: int ++
+    default: 100 ++
+    The maximum volume value the slider should display and set.
+
+*orientation*: ++
+    typeof: string ++
+    default: horizontal ++
+    The orientation of the slider. Can be either `horizontal` or `vertical`.
+
+*device*: ++
+    typeof: string ++
+    The name of the preferred device to control. If left empty, a device will be chosen automatically.
+
+*expand*: ++
+	typeof: bool ++
+	default: false ++
+	Enables this module to consume all left over space dynamically.

+
+# STYLE
+
+The slider is a component with multiple CSS Nodes, of which the following are exposed:
+
+*#backlight-slider*: ++
+    Controls the style of the box *around* the slider and bar.
+
+*#backlight-slider slider*: ++

+    Controls the style of the part of the bar that has not been filled.
+
+*#backlight-slider highlight*: ++
+    Controls the style of the part of the bar that has been filled.
