Virtual Keyboard using HTML, CSS(SCSS) and JavaScript – Coding Torque

Share your love

Hello Guys! Welcome to Coding Torque. In this blog, I’m going to explain to you how to make a Virtual Keyboard using HTML, CSS and JavaScript. You can use this effect on your website/portfolio to showcase any skills/features. This will be a step-by-step guide. Let’s get started 🚀.

Before we start, here are some JavaScript Games you might like to create:

1. Snake Game using JavaScript

2. 2D Bouncing Ball Game using JavaScript

3. Rock Paper Scissor Game using JavaScript

4. Tic Tac Toe Game using JavaScript

5. Whack a Mole Game using JavaScript


I would recommend you don’t just copy and paste the code, just look at the code and type by understanding it.
