📱 Project Alert: QR Code Generator Web App

In today’s challenge, I built a QR Code Generator using HTML, CSS, and JavaScript. This application allows users to generate QR codes in real time, customize the size, and download them instantly as PNG images.

This project helped me improve my understanding of DOM manipulation, event handling, and third-party library integration.

📐 Size Selection – Choose QR sizes from 100×100 to 1000×1000
