## Overview

WiFi QR Generator is a browser-only utility: a user enters an SSID and password, the app escapes them into a WiFi payload, generates and displays a QR code, and supports printing or JPG download. The README documents the responsive, animated interface and print styling; the sampled JavaScript shows input handling, QR generation, validation, and export. The HTML, CSS, and QR engine are represented from the documented project structure, but their source was not sampled.

Main entry points: [`script.js`](https://github.com/rahulde2007/wifi-qr-generator/blob/main/script.js) (Input and feedback), [`index.html`](https://github.com/rahulde2007/wifi-qr-generator/blob/main/index.html) (QR preview), [`style.css`](https://github.com/rahulde2007/wifi-qr-generator/blob/main/style.css) (Responsive and print styling)
