Top 35 CSS Interview Questions for Beginners
Here are the top 35 CSS interview questions—a key part of CSS and C interview questions—you might face in an Indian job interview. Each comes with a simple answer, explanation, and example—perfect for beginners preparing for CSS and C interview questions!
1. What is CSS and why is it used?
- Answer: CSS stands for Cascading Style Sheets. It styles HTML elements to make websites look nice.
- Explanation: Without CSS, websites are just plain text. It controls colors, fonts, and layouts—a common topic in CSS and C interview questions.
- Example: p { color: red; } makes all paragraph text red.
2. What is the CSS box model?
- Answer: The box model shows how elements are built with content, padding, borders, and margins.
- Explanation: Every HTML element is a “box” with these parts, often asked in CSS and C interview questions.
- Example: div { padding: 10px; border: 2px solid black; margin: 15px; }.
3. How do you center a div horizontally?
- Answer: Use margin: 0 auto; with a set width.
- Explanation: This balances the left and right margins automatically—a practical CSS and C interview question.
- Example: div { width: 50%; margin: 0 auto; }.
4. What’s the difference between relative and absolute positioning?
- Answer: Relative moves an element from its normal spot; absolute positions it based on its nearest positioned parent.
- Explanation: Relative keeps its space; absolute doesn’t—expect this in CSS and C interview questions.
- Example: .relative { position: relative; top: 10px; } .absolute { position: absolute; top: 20px; }.
5. What is Flexbox?
- Answer: Flexbox is a CSS tool for arranging items in a container flexibly.
- Explanation: It’s perfect for responsive layouts, a hot topic in CSS and C interview questions.
- Example: .container { display: flex; justify-content: space-between; }.
6. What are media queries?
- Answer: Media queries adjust styles based on device size or type.
- Explanation: They make websites work on phones, tablets, or PCs—key for CSS and C interview questions.
- Example: @media (max-width: 600px) { body { font-size: 14px; } }.
7. What is z-index?
- Answer: z-index controls the stacking order of overlapping elements.
- Explanation: Higher values go on top, a tricky part of CSS and C interview questions.
- Example: .top { position: absolute; z-index: 10; }.
