This question evaluates your front-end development skills, particularly your ability to create applications that work seamlessly across devices and browsers. Recruiters want to see your knowledge of responsive design principles, CSS techniques, and testing tools. A strong answer would include specific steps you take during development and testing, as well as examples of tools like BrowserStack or Chrome DevTools.

Answer Example

To ensure cross-browser compatibility and responsive design, I follow a mobile-first approach using media queries in CSS to adapt layouts for different screen sizes. I also use modern CSS frameworks like Bootstrap or Tailwind for consistency and test the application on various browsers using tools like BrowserStack. For instance, in a recent project, I encountered layout issues on older versions of Internet Explorer. I resolved them by using polyfills and ensuring fallback styles for unsupported features. Additionally, I focus on semantic HTML to improve accessibility and maintainability.
