    A. Definition of QR code

    -QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan.

What Is GENERATE QR CODE USING HTML AND CSS and How Does It Work?

GENERATE QR CODE USING HTML AND CSS is a process of creating a QR code using HTML and CSS. A QR code is a type of barcode that can be scanned by a smartphone or other device to provide information such as a website URL, contact information, or a text message.

    </div>

    <script>

        function generateQR(){

            document.querySelector("#qr-image").style.display = "block";

            let QRtext = document.querySelector("#text").value;

            if(QRtext.trim().length == 0){

                document.querySelector("#qr-image .error").innerHTML = "Please type something...";

                document.querySelector("#img").style.display = "none";

            }else{

                document.querySelector("#img").style.display = "block";

                document.querySelector("#qr-image .error").innerHTML = "";

                document.querySelector("#img").src = "https://api.qrserver.com/v1/create-qr-code/?size=240x240&data=" + QRtext;

            }
