Discover how to make a QR Generator by using JavaScript as the programming language.
Html should be used to code the structure of the QR generator project.
Style the QR generator using CSS.
Use JavaScript to make the QR generator dynamic.

Structure (HTML):
Like the latter in the calculator example, it describes the general layout of a page in HTML.
To create the title, you should type “QR Code Generator”.
The body section has the greatest density of information and is the central part of any article.
Within the body section, there is a div which has a class of container and a div which has a class of box. This generates an enclosure where the layout of the QR generator will reside.
Within the box div:
A label element describes the action that should be taken, thus the phrase “Enter Text or URL”.
An input field of type text with a hint that reads, ‘Enter Text or URL’ is given for users to enter their details. The input field of this identifier has an ID of qrText.
As for the location of the QR code image to be generated, a div with the ID of imgBox would probably contain the image.
Inside imgBox there is an img element with an ID qrImg that shows the QR code image. For now, the src attribute for the image is empty.
A clickable button which has the text “Generate QR Code” is used to trigger the method of generating the QR code. It calls the generateQR() function available in the Javascript file.
Functionality (Javascript – qr.js assumed):
The generateQR() function (defined in the external Javascript file qr.js) is likely responsible for:
Considering the value that was inputted in the qrText field.
Applying a QR code generation library that generates QR code image from the given text/URL.
It was replacing the src attribute of the qrImg element with the data URL of the QR code image generated dynamically. This makes it possible to display the image in the div tag that is imgBox.
