+## Slider
+
+A `Slider` is a bar and a handle that selects a single value from a range of values.
+There exists both `Slider` and `VerticalSlider` depending on which orientation you need.
+
+<div align="center">
+    <img src="sliders.gif">
+</div>
+
+You can run it with `cargo run`:
+
+```
+cargo run --package slider
+```
