Glassmorphic Calculator using HTML, CSS and JavaScript

Hello Guys! Welcome to Coding Torque. In this blog, I’m going to explain to you how to make a glassmorphic calculator using HTML, CSS, and JavaScript. This will be a step-by-step guide including HTML and CSS. 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.
