Step 1: HTML Structure

Our journey begins with laying the foundation — the HTML structure. This code outlines the fields users will interact with.

// Responsive Registration Form in HTML, CSS and Java Script
<div class="wrapper">
      <h1 class="title">Registration</h1>
      <form action="#">
        <div class="info-section">
          <div class="input-field">
            <label for="fullName">Full Name</label>
            <input type="text" id="fullName" name="fullName" placeholder="Enter Full Name" />
          </div>
          <div class="input-field">
            <label for="username">Username</label>
            <input type="text" id="username" name="username" placeholder="Enter Username" />
          </div>
          <div class="input-field">
            <label for="email">Email</label>
            <input type="email" id="email" name="email" placeholder="Enter Email" />
          </div>
          <div class="input-field">
            <label for="phoneNumber">Phone Number</label>
            <input type="text" id="phoneNumber" name="phoneNumber" placeholder="Enter Phone Number" />
          </div>
          <div class="input-field">
            <label for="password">Password</label>
            <input type="password" id="password" name="password" placeholder="Enter Password" />
          </div>
          <div class="input-field">

            <input type="password" id="confirmPassword" name="confirmPassword" placeholder="Confirm Password" />
          </div>
        </div>
        <div class="gender-details-box">
          <span class="gender-label">Gender</span>
          <div class="gender-group">

Step 2: CSS Styling:

 @import url("https://fonts.googleapis.com/css2?family=Poppins:wght@200;300;400;500;600;700&display=swap");
// Responsive Registration Form in HTML, CSS and Java Script
* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
  font-family: "Poppins", sans-serif;
}

body {
  display: flex;
  height: 100vh;
  justify-content: center;
  align-items: center;
  background: -webkit-linear-gradient(left, #5f2c82, #49a09d);
  background-size: cover;
}
// Responsive Registration Form in HTML, CSS and Java Script
.wrapper {
  width: 100%;
  max-width: 650px;
  background: rgba(243, 242, 242, 0.5);
  padding: 28px;
  margin: 0 28px;
  border-radius: 10px;
}

.title {
  font-size: 26px;
  font-weight: 600;
  text-align: center;
  padding-bottom: 6px;
  color: white;
  border-bottom: solid 1px white;
}

.info-section {
  display: flex;
  flex-wrap: wrap;
  justify-content: space-between;
  padding: 20px 0;
}

.input-field:nth-child(2n) {
  justify-content: end;
}
// Responsive Registration Form in HTML, CSS and Java Script
.input-field {
  display: flex;
  flex-wrap: wrap;
  width: 50%;
  padding-bottom: 15px;
}

.input-field label {
  width: 95%;
  color: white;
  font-size: 20px;
  font-weight: 400;
  margin: 5px 0;
}

.input-field input {
  height: 40px;
  width: 95%;
  border-radius: 7px;
  outline: none;
  border: 1px solid grey;
  padding: 0 10px;
}

.gender-label {
  color: white;
  font-size: 24px;
  font-weight: 600;
  border-bottom: 1px solid white;
}

.gender-group {
  margin: 15px 0;
  color: white;
}

.gender-group label {
  padding: 0 20px 0 5px;
}

.gender-group label,
.gender-group input,
.submit-button input {
  cursor: pointer;
}

.submit-button {
  margin-top: 40px;
}

.submit-button input {
  display: block;
  width: 100%;
  margin-top: 10px;
  font-size: 20px;
  padding: 10px;
  border: none;
  border-radius: 3px;
  color: rgb(255, 255, 255);
  background: -webkit-linear-gradient(left, #5f2c82, #49a09d);
}
// Responsive Registration Form in HTML, CSS and Java Script
.submit-button input:hover {
  background: -webkit-linear-gradient(left, #5f2c82, #49a09d, #5f2c82, #49a09d);
  color: rgb(255, 255, 255);
}

@media (max-width: 600px) {
  .wrapper {
    min-width: 280px;
  }

  .input-field {
    margin-bottom: 12px;
    width: 100%;
  }

  .input-field:nth-child(2n) {
    justify-content: space-between;
  }

  .gender-group {
    display: flex;
    justify-content: space-between;
    width: 100%;
  }

  .info-section {
    max-height: 380px;
    overflow: auto;
  }

  .info-section::-webkit-scrollbar {
    width: 0;
  }
}

Step 3: Validations with JavaScript:

// Responsive Registration Form in HTML, CSS and Java Script
<script>
      document.addEventListener("DOMContentLoaded", function() {
        const form = document.querySelector("form");
    
        form.addEventListener("submit", function(event) {
          // Prevent the form from submitting
          event.preventDefault();
    
          // Validate email
          const email = document.getElementById("email").value;
          const emailPattern = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
          if (!emailPattern.test(email)) {
            alert("Please enter a valid email address.");
            return;
          }
    
          // Validate phone number (only numbers)
          const phoneNumber = document.getElementById("phoneNumber").value;
          const phonePattern = /^\d+$/;
          if (!phonePattern.test(phoneNumber)) {
            alert("Phone number must contain only numbers.");
            return;
          }
    
          // Validate password match
          const password = document.getElementById("password").value;
          const confirmPassword = document.getElementById("confirmPassword").value;
          if (password !== confirmPassword) {
            alert("Passwords do not match.");
            return;
          }
    
          // If all validations pass, submit the form
          form.submit();
        });
      });
    </script>
