Box shadows in CSS can be layered. You can apply multiple box shadows for the same element. This is generally used for a rich and realistic box shadow, but what's stopping us hacking this 🤭
▪️ Here we create a box shadow with 0 blur and some offset to create a duplicate layer
▪️ Then we create a similar layer but a pixel more of spread, to create a pseudo border
▪️ Finally another actual box shadow layer

✅ 20 Medium-Level Web Development Interview Questions (with Detailed Answers)
1. What is the difference between HTML, CSS, and JavaScript
• HTML: Structures content
• CSS: Styles content
• JavaScript: Adds interactivity and dynamic behavior
2. What is responsive web design
Designing websites that adapt to different screen sizes and devices using flexible grids, media queries, and fluid layouts.
3. What are semantic HTML elements
Elements that clearly describe their meaning (e.g.,
4. What is the DOM
Document Object Model — a tree-like structure representing HTML elements. JavaScript can manipulate it to update content dynamically.
5. What is the difference between GET and POST methods
• GET: Sends data via URL, used for fetching
• POST: Sends data in body, used for submitting forms securely
6. What is the box model in CSS
Every HTML element is a box:
Content → Padding → Border → Margin
7. What is the difference between relative, absolute, and fixed positioning in CSS
• Relative: Moves element relative to its normal position
• Absolute: Positions element relative to nearest positioned ancestor
• Fixed: Stays in place even when scrolling
8. What is the difference between == and === in JavaScript
•
•
9. What is event bubbling in JavaScript
Events propagate from child to parent elements. Can be controlled using
10. What is the difference between localStorage and sessionStorage
•
•
11. What is a RESTful API
An architectural style for designing networked applications using HTTP methods (GET, POST, PUT, DELETE) and stateless communication.
12. What is the difference between frontend and backend development
• Frontend: Client-side (UI/UX, HTML/CSS/JS)
• Backend: Server-side (databases, APIs, authentication)
13. What are common HTTP status codes
• 200 OK
• 404 Not Found
• 500 Internal Server Error
• 403 Forbidden
• 301 Moved Permanently
14. What is a promise in JavaScript
An object representing the eventual completion or failure of an async operation.
States: pending, fulfilled, rejected
15. What is the difference between synchronous and asynchronous code
• Synchronous: Executes line by line
• Asynchronous: Executes independently, doesn’t block the main thread
16. What is a CSS preprocessor
Tools like SASS or LESS that add features to CSS (variables, nesting, mixins) and compile into standard CSS.
17. What is the role of frameworks like React, Angular, or Vue
They simplify building complex UIs with reusable components, state management, and routing.
18. What is the difference between SQL and NoSQL databases
• SQL: Structured, relational (e.g., MySQL)
• NoSQL: Flexible schema, document-based (e.g., MongoDB)
19. What is version control and why is Git important
Version control tracks changes in code. Git allows collaboration, branching, and rollback. Platforms: GitHub, GitLab, Bitbucket
20. How do you optimize website performance
• Minify CSS/JS
• Use lazy loading
• Compress images
• Use CDN
• Reduce HTTP requests
