This document CSS shows how to write the HTML and CSS to style the default visual slider. You need to add additional functions in Javascript in order to set min, max, step, marks for slider, and to control position of slider handles if you tend to implement a complete slider using HTML, JS and CSS without using a framework.

Therefore, we invite you to consult the Slider documents in Angular/ React/ Vue/ Web-components that show you how to easily create and control a Quantum slider.
