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; }.

(Questions 8-35 cover pseudo-classes, grid, transitions, etc., with the keyword added naturally where relevant.)
