QR Code Generator
Hello Guys! Welcome to Coding Torque. In this blog, I'm going to explain to you how to make a QR Code Generator using HTML, CSS, and JavaScript. This will be a step-by-step guide. Let's get started 🚀.
Let's go step by step:
Step 1: IMPORT google fonts
Now let's import the fonts using Google Fonts API. Below is the code for Poppins Font. Paste the below code in head tag.
<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
<link href="https://fonts.googleapis.com/css2?family=Poppins&display=swap" rel="stylesheet">Step 2: HTML Code
<!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=="

</div>
<button type="button" class="generateBtn" onclick="generateQRCode()">Generate QR Code</button>
</form>

.heading {

margin-bottom: 20px;
padding: 10px 0;
width: 100%;

#website {

Step 4: JavaScript Code
function generateQRCode() {
let website = document.getElementById("website").value;
if (website) {
let qrcodeContainer = document.getElementById("qrcode");
qrcodeContainer.innerHTML = "";
new QRCode(qrcodeContainer, website);

} else {
alert("Please enter a valid URL");
}
}
