What are HTML & CSS?

HTML and CSS are the foundation of web development. HTML provides structure and semantics, while CSS handles styling and layout. Together, they enable developers to create accessible, responsive, and visually appealing web experiences.

HTML & CSS interviews test your understanding of semantic markup, accessibility, responsive design, and modern CSS features like Flexbox and Grid. You'll discuss browser compatibility and best practices for maintainable stylesheets.

Strong HTML & CSS fundamentals are essential for frontend development. Master these technologies and you'll build the foundation for advanced frontend skills.

Reading answers is not the same as giving them. Sit a full mock interview and get scored on how you actually explain them.
