2. What is CSS and how does it work with HTML?

How it Works:

• Selectors: CSS uses selectors to apply styles to HTML elements. For example, p { color: red; } turns all paragraph text red.
• Cascade: Styles can override each other based on their specificity and order.
• Separation of Concerns: CSS separates design from content, simplifying updates.

3. Describe the concept of responsive design.

Answer: Responsive design ensures that a website looks good on all devices, from desktops to smartphones. It uses flexible layouts and media queries.

Key Features:

• Fluid Grid Layouts: Elements are sized in percentages, allowing them to resize with the screen width.
• Flexible Images: Images adjust to fit their container, avoiding overflow.
• Media Queries: CSS rules apply based on device characteristics, such as screen size (e.g., @media screen and (max-width: 600px) { ... }).

Role-Specific Questions

4. What are the key differences between client-side and server-side scripting?

Answer:

• Client-Side Scripting: Runs in the user’s browser and includes JavaScript, HTML, and CSS. It handles interactive features and immediate feedback.
• Server-Side Scripting: Executes on the server before sending the page to the browser. Examples include PHP and Node.js. It manages tasks like database access and generating dynamic content.

5. How would you optimize a website’s performance?

Answer: To enhance a website’s speed and efficiency, you can:

• Minify Files: Reduce the size of CSS, JavaScript, and HTML files by removing unnecessary characters.
• Optimize Images: Use proper formats and compress images to reduce their size.
• Enable Caching: Store static resources in users’ browsers to speed up repeat visits.
• Use a CDN: Distribute content across servers worldwide to improve load times.
• Reduce HTTP Requests: Combine files and use CSS sprites to minimize server requests.

6. Explain the box model in CSS.

Answer: The CSS box model defines the layout of elements on a web page. It includes:

• Content: The actual content of the box, such as text or an image.
• Padding: Space between the content and the border, providing inner spacing.
• Border: A line surrounding the padding and content, which can be styled.
• Margin: Space outside the border, creating distance from other elements.

Understanding the box model is essential for designing layouts and fixing issues.

7. What are some common web development tools you are familiar with?

Answer: Common tools for web development include:

• Text Editors/IDEs: Visual Studio Code, Sublime Text, and Atom for coding.
• Version Control Systems: Git, used with GitHub or GitLab for tracking changes and collaboration.
• Browsers: Chrome, Firefox, and Edge for testing and debugging.
• Build Tools: Webpack and Gulp for automating tasks like file minification.

The server side used Node.js and Express for handling requests, with MongoDB for data storage. I also integrated Stripe for payment processing.”

9. What is AJAX and how is it used in web development?

Answer: AJAX (Asynchronous JavaScript and XML) allows dynamic web pages. It updates parts of a page without reloading the whole page.

Uses:

• Fetch Data: Retrieve and display data from the server without refreshing.
• Submit Forms: Send form data asynchronously.
• Load New Content: Add content dynamically, such as loading more results as the user scrolls.

10. How do you handle cross-browser compatibility issues?

Answer: To manage cross-browser compatibility:

• Test Across Browsers: Check how your site performs on various browsers and devices.
• Use CSS Prefixes: Apply vendor prefixes for newer CSS features.
