Step by step form validation using HTML, CSS and JavaScript

Welcome to Coding Torque! Today, we are going to create a comprehensive form validation system using HTML, CSS and JavaScript. This project will provide you with a step-by-step guide on how to create a secure and efficient form validation system. We will be covering topics such as creating the HTML structure, styling the form with CSS, and writing the JavaScript code for validating the form data. By the end of this project, you will have a fully functional form validation system that can be used in any web application. So let’s get started!

I would recommend you don’t just copy and paste the code, just look at the code and type by understanding it.

HTML Code

Starter Template

<!doctype html>
<html lang="en">

<head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <!-- CSS -->
    <link rel="stylesheet" href="style.css">

    <title>Step By Step Form using JavaScript - Coding Torque</title>

<body>
    <!-- Further code here -->

    <script src="https://code.jquery.com/jquery-3.6.3.js"

    <script src="script.js"></script>
</body>

</html>

Paste the below code in your `<body>` tag.

<div class="modal-wrap">
    <div class="modal-header"><span class="is-active"></span><span></span><span></span></div>
    <div class="modal-bodies">
        <div class="modal-body modal-body-step-1 is-showing">

                </label>
                <div class="text-center fade-in">
                    <div class="button">Next</div>
                </div>
            </form>
        </div>
        <div class="modal-body modal-body-step-3">
            <div class="title">Step 3</div>
            <div class="description">Check your email for the game results.</div>
