Set up your development environment

To get started with Slider control, you can clone the Essential JS 2 quickstart project, and install the packages by using the following commands.

git clone https://github.com/syncfusion/ej2-quickstart.git quickstart
cd quickstart
npm install

The project is preconfigured with the common settings (src/styles/styles.css, system.config.js) to start with all Essential JS 2 controls.

Adding CSS reference

Combined CSS files are available in the Essential JS 2 package root folder. This can be referenced in your [src/styles/styles.css] using the following code.

@import '../../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-inputs/styles/material.css';

Adding Slider to the project

Add the div element with the id attribute #slider inside the body tag in your index.html.
