This project is a simple interactive quiz application built with HTML, CSS, and JavaScript. It allows users to answer multiple-choice questions, submit their answers, and receive an instant score. The app demonstrates basic form handling, dynamic content updates, and DOM manipulation in JavaScript.
? Project Overview
Features
- Multiple Choice Questions: Three questions with multiple answer options.
- Submit Button: Allows users to submit their answers.
- Instant Scoring: Displays the user's score immediately after submission.
- Interactive Design: Simple styling and hover effects for better user experience.
Technologies Used
- HTML: For structuring the content.
- CSS: For styling the quiz interface.
- JavaScript: For adding interactivity and processing the answers.

? 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 (
- Radio Buttons () for selecting answers.
- Submit Button to check the answers.
- Result Div to display the score.
<form> <h3> ? <strong>CSS (styles.css)</strong> </h3> <p>The CSS file styles the quiz interface, making it visually appealing and responsive.</p> <p><strong>Key Styling Concepts:</strong></p>
- 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!`; });

There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSSCounters is a tool for creating automatic numbers. 1. Basic usage: define and operate counters through counter-reset and counter-increment, such as "SectionX." before h2. 2. Advanced usage: Use nested counters to create complex numbers, such as chapter and section numbers. 3. Notes: Ensure the counter is reset correctly, optimize performance, and simplify counter logic. 4. Best practice: clear naming, define counters in CSS, and use counter-increment and counter-reset reasonably.
