Explanation

Answer Example

To ensure cross-browser compatibility, I follow a few key steps. First, I write clean, standards-compliant code by adhering to W3C guidelines and using modern CSS and JavaScript features with fallbacks for unsupported browsers. I use tools like Autoprefixer to manage vendor prefixes automatically. During development, I test the application on all major browsers (Chrome, Firefox, Safari, Edge) and use tools like BrowserStack for older versions or less common browsers. I also employ progressive enhancement, ensuring basic functionality is available on all browsers while advanced features enhance the experience on modern ones. Debugging tools such as DevTools help identify and resolve browser-specific issues quickly. Finally, I document compatibility considerations and maintain a testing checklist to ensure quality moving forward.
