If your app displays incorrectly in specific browsers, test it using browser developer tools to identify CSS or JavaScript issues. Ensure that your code adheres to web standards and is compatible with all major browsers.

Cross-browser compatibility is essential for providing a consistent user experience across different platforms. If your application is not displaying correctly in certain browsers, begin by testing it using the developer tools available in those browsers. These tools allow you to inspect elements, check console logs for JavaScript errors, and view the CSS styles applied to various components. Identify any discrepancies in how elements are rendered and note any error messages that may indicate underlying issues. A common problem is the use of CSS properties that are not supported in all browsers; consulting resources like Can I Use can help you verify compatibility. Ensure that your code adheres to web standards and avoid using vendor-specific prefixes unless absolutely necessary. If you’re utilizing modern JavaScript features, consider using a transpiler like Babel to ensure compatibility with older browsers. Conducting thorough testing on various devices and browser versions is crucial; tools like BrowserStack or Sauce Labs can help you simulate these environments. Additionally, consider implementing responsive design principles to enhance compatibility across different screen sizes. Gathering user feedback about their experiences on various browsers can provide insights into specific issues that need addressing. By systematically identifying and resolving cross-browser issues, you can enhance the accessibility and usability of your application for all users.
