CSS (Cascading Style Sheets) is used to style and layout web pages, allowing developers to control the appearance and design of a website. - Can you explain the difference between a static and a dynamic website?
A static website displays the same content to every visitor, while a dynamic website generates content based on user interactions or other variables. - What is the purpose of the doctype declaration in HTML?
The doctype declaration defines the version of HTML being used and helps the browser render the page correctly. - What are meta tags in HTML, and why are they important?
Meta tags provide metadata about the HTML document, such as descriptions, keywords, and author information, which can influence SEO and page indexing. - What is JavaScript, and how is it used in web development?
JavaScript is a programming language used to create interactive and dynamic content on websites, such as form validation and animations. - What is a responsive web design, and why is it important?
Responsive web design ensures that a website looks and functions well on various devices, from desktops to mobile phones. - What is a web browser, and what role does it play in web development?
A web browser is software that retrieves and displays web pages from the internet, rendering HTML, CSS, and JavaScript files. - How do you create a hyperlink in HTML?
A hyperlink is created using the <a> tag in HTML, with the href attribute specifying the destination URL. - What is the box model in CSS?
The box model describes the layout of elements on a page, including content, padding, border, and margin areas. - Can you explain the difference between an ID and a class in CSS?
An ID is a unique identifier for a single HTML element, while a class can be used to style multiple elements. - What is a favicon, and how do you add one to a website?
A favicon is a small icon associated with a website, typically displayed in the browser tab. It can be added using the <link> tag in the <head> section of HTML. - What is a content management system (CMS)?
A CMS is software that allows users to create, manage, and modify content on a website without needing extensive coding knowledge. - What are the advantages of using a CSS preprocessor like SASS?
SASS allows developers to use variables, nested rules, and functions in their CSS, making the code more maintainable and scalable. - What is the role of the <head> element in an HTML document?
The <head> element contains meta-information about the document, such as the title, character set, and links to stylesheets and scripts. - How do you create a form in HTML?
A form is created using the <form> tag in HTML, with various form elements like <input>, <textarea>, and <button> to capture user input. - What is the difference between display: none and visibility: hidden in CSS?
display: none removes an element from the layout flow, while visibility: hidden hides the element but still occupies space. - What is a web server, and what role does it play in website development?
A web server stores, processes, and delivers web pages to users upon request, handling HTTP/HTTPS protocols. - How do you optimize images for the web?
Images can be optimized by compressing file sizes, using appropriate file formats (JPEG, PNG, WebP), and using tools like Photoshop or online compressors. - What is version control, and why is it important in web development?
Version control, such as Git, tracks changes to code, allowing developers to collaborate, revert to previous versions, and manage project history.

- What are RESTful APIs, and how do they integrate with websites?
RESTful APIs allow different applications to communicate over the web using HTTP methods like GET, POST, PUT, and DELETE. - Explain the concept of MVC architecture in web development.
MVC (Model-View-Controller) is a design pattern that separates an application into three interconnected components, promoting organized and modular code. - How do you ensure cross-browser compatibility for your website?
Cross-browser compatibility is ensured by testing on different browsers, using feature detection libraries like Modernizr, and applying polyfills for unsupported features. - What are web components, and why are they important in modern web development?
Web components are reusable, encapsulated HTML elements that can be used across web projects, promoting code reuse and consistency. - What is the difference between client-side and server-side rendering?
Client-side rendering generates HTML in the browser using JavaScript, while server-side rendering generates HTML on the server and sends it to the client. - How do you optimize a website’s performance?
Website performance can be optimized by minimizing HTTP requests, compressing images and files, enabling caching, and using a content delivery network (CDN). - What is a Single Page Application (SPA), and how does it work?
A SPA is a web application that loads a single HTML page and dynamically updates content as the user interacts, providing a seamless experience without full-page reloads. - What is AJAX, and how does it improve user experience?
AJAX (Asynchronous JavaScript and XML) allows web pages to update asynchronously by exchanging data with the server behind the scenes, without reloading the entire page. - How do you implement security measures in a web application?
Security measures include input validation, using HTTPS, implementing Content Security Policies (CSP), and protecting against common threats like SQL injection and XSS. - What is Progressive Web App (PWA), and what are its benefits?
PWA is a web application that uses modern web technologies to deliver an app-like experience, including offline functionality, push notifications, and fast load times. - How do you use Docker in web development?
Docker is a platform that allows developers to package an application and its dependencies into a container, ensuring consistency across different environments. - What are microservices, and how do they differ from a monolithic architecture?
Microservices architecture breaks down an application into smaller, independent services, improving scalability and maintainability, unlike a monolithic architecture where everything is interconnected. - How do you manage state in large web applications?
State management can be handled using libraries like Redux or Context API, which help maintain a consistent state across the application. - What is the importance of SEO in web development, and how do you implement it?
SEO is crucial for making a website discoverable by search engines. Implement SEO by optimizing meta tags, using clean URLs, ensuring mobile-friendliness, and creating high-quality content. - What is CORS, and how do you handle it in web development?
CORS (Cross-Origin Resource Sharing) is a security feature that controls how resources on a web page can be requested from another domain. It’s handled by setting proper headers on the server. - How do you use WP-CLI for managing WordPress sites?
WP-CLI is a command-line tool for managing WordPress installations, allowing developers to perform tasks like updates, backups, and content management without using the web interface. - What is a headless CMS, and how does it differ from traditional CMS?
A headless CMS decouples the content management backend from the presentation layer, allowing developers to use any front-end technology to display content. - How do you troubleshoot performance issues on a website?
Performance issues can be troubleshooted by using tools like Google Lighthouse, identifying bottlenecks, optimizing images, minifying CSS/JS, and reducing server response times. - What is the role of the .htaccess file in web development?
