📝 Code Breakdown

📄 HTML (index.html)

The HTML file creates the structure of the quiz, including questions, answer choices, and a submit button.

Key Elements:

• Form (<form>) to group quiz questions.
• Radio Buttons (<input type="radio">) for selecting answers.
• Submit Button to check the answers.
• Result Div to display the score.

<form id="quiz-form">
  <div class="question">
    <p>1. What is the capital of France?</p>
    <label><input type="radio" name="q1" value="Paris"> Paris</label>
    <label><input type="radio" name="q1" value="Rome"> Rome</label>
    <label><input type="radio" name="q1" value="London"> London</label>
  </div>

  <button type="button" id="submit-btn">Submit Answers</button>
</form>

<div id="result"></div>

🎨 CSS (styles.css)

The CSS file styles the quiz interface, making it visually appealing and responsive.

Key Styling Concepts:

• Layout: Flexbox for alignment and spacing.
• Hover Effects: Button changes color when hovered.
• Box Shadow: For a modern card-like appearance.

button {
  background-color: #28a745;
  color: #fff;
  padding: 10px 15px;
  border: none;
  border-radius: 5px;
  cursor: pointer;
}

button:hover {
  background-color: #218838;
}

⚙️ JavaScript (script.js)

The JavaScript file handles the quiz logic, processes user answers, and displays the score.

Key Concepts:

• Event Listeners: To detect when the user clicks the submit button.
• Form Handling: Accessing user-selected answers.
• DOM Manipulation: Updating the result section with the user's score.

document.getElementById('submit-btn').addEventListener('click', function() {
  const answers = {
    q1: 'Paris',
    q2: '4',
    q3: 'Blue'
  };

  let score = 0;
  const form = document.getElementById('quiz-form');

  if (form.q1.value === answers.q1) score++;
  if (form.q2.value === answers.q2) score++;
  if (form.q3.value === answers.q3) score++;

  document.getElementById('result').textContent = `You scored ${score} out of 3!`;
});
