How do you ensure cross-browser compatibility for websites you develop?

Ensuring Cross-Browser Compatibility in Website Development

As a web developer, ensuring cross-browser compatibility is crucial to deliver a seamless user experience. To achieve this, I follow a structured approach that involves:

1. Testing on Multiple Browsers: I regularly test websites on popular browsers such as Google Chrome, Mozilla Firefox, Safari, and Microsoft Edge to ensure proper functionality and responsiveness across different platforms.
2. Using Vendor Prefixes: When using CSS properties that may require vendor prefixes for compatibility, I ensure to include all necessary prefixes to maintain consistency across browsers.
3. Validating HTML and CSS: I make sure to validate all HTML and CSS code using tools like W3C Markup Validation Service to identify and fix any errors that may affect cross-browser compatibility.
4. Utilizing Polyfills: For handling inconsistencies in browser support for certain features, I implement polyfills that provide fallback mechanisms to ensure functionality is maintained across different browsers.

By following these steps and staying updated on the latest web standards, I can guarantee a seamless cross-browser experience for all users accessing the websites I develop.
