Create an Online Payment Project using HTML CSS & JavaScript

Last Updated : 15 Jul, 2024

In this article, We will create a responsive online payment page using HTML, CSS & Javascript.

Here, we will learn about the project's structure before beginning to code each page individually. To ensure adequate understanding, we also gave the project's output after it was created.

Prerequisites:

Approach

Create "index.html" file, this is the skeleton of the project. Create the main structure using outer <div>, and other HTML tags.
Create two columns in the <form>, one for the billing address and the other for the payment. In this project, we will create a payment using cards only, that is why we will use an image of cards after that added the checkout button.
Now add the CSS file <head> section of "index.html". Add background color, margin, and padding. Here we added responsiveness, and hover effects for a better view.
Now add "index.js" to the javascript file before the <body> tag ends in the "index.html" file. So that the javascript will be rendered with the body tag in web browsers.
In JavaScript, we will add the logic to split the card number when the user inputs their card number.

Project Structure:

Example: This example shows the implementation of above-explained approach.
