Hello Guys! Welcome to Coding Torque. In this blog, I'm going to explain to you how to make a Detect Operating System using HTML, CSS and JavaScript. This will be a step-by-step guide. Let's get started 🚀.

## **Step 1: Import Fontawesome CDN**
Import the font awesome CDN in our HTML `<head>` tag. fontawesome is a library that is used for icons on a website.

```html
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.1/css/all.min.css"
        integrity="sha512-+4zCK9k+qNFUR5X+cKL9EIR+ZOhtIloNl9GIKS57V1MyNsYpYcUrUeQc9vNfzsWfV28IaLL3i96P9sdNyeRssA=="
        crossorigin="anonymous" />
```

## **Step 2 : HTML Code**

```html
<!DOCTYPE html>
<html lang="en">

<head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <!-- Font Awesome Icons  -->
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.1/css/all.min.css"
        integrity="sha512-+4zCK9k+qNFUR5X+cKL9EIR+ZOhtIloNl9GIKS57V1MyNsYpYcUrUeQc9vNfzsWfV28IaLL3i96P9sdNyeRssA=="
        crossorigin="anonymous" />
