body {
  font-family: Arial, sans-serif;
  background-color: #f4f4f9;
  margin: 0;
  padding: 20px;
}
 
.calculator {
  max-width: 400px;
  margin: auto;
  background: #ffffff;
  padding: 20px;
  border-radius: 10px;
  box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
}
 
h1 {
  text-align: center;
  font-size: 24px;
  color: #333;
}
 
.form-group {
  margin-bottom: 15px;
}
 
label {
  display: block;
  font-size: 16px;
  color: #555;
  margin-bottom: 5px;
}
 
input {
  width: 100%;
  padding: 10px;
  border: 1px solid #ddd;
  border-radius: 5px;
  font-size: 14px;
}
 
button {
  width: 100%;
  padding: 10px;
  background-color: #007bff;
  border: none;
  color: white;
  font-size: 16px;
  border-radius: 5px;
  cursor: pointer;
}
 
button:hover {
  background-color: #0056b3;
}
 
.result {
  margin-top: 20px;
  font-size: 18px;
  color: #333;
  text-align: center;
}

Step 3: Adding JavaScript

Implement logic to calculate the total cost dynamically:

?

document.getElementById("calculateBtn").addEventListener("click", function () {
  const adSpend = parseFloat(document.getElementById("adSpend").value) || 0;
  const contentCreation = parseFloat(document.getElementById("contentCreation").value) || 0;
  const managementFees = parseFloat(document.getElementById("managementFees").value) || 0;
 
  const totalCost = adSpend + contentCreation + managementFees;
 
  document.getElementById("totalCost").textContent = `Total Cost: ₹${totalCost.toFixed(2)}`;
});

Testing the Calculator

  1. Copy and paste the code into three files: index.html, styles.css, and script.js.
  2. Open index.html in your browser.
  3. Enter different values to see the total cost update instantly.
