How can I ensure my website is cross-browser compatible?

Cross-browser compatibility means your website looks and works properly across all major web browsers, such as Chrome, Firefox, Safari, Edge, and Opera. It's essential because users access your site from different browsers and devices—what works in one might break in another.

? Best Practices to Ensure Cross-Browser Compatibility:

1. Use Standard-Compliant Code
   Stick to HTML5, CSS3, and modern JavaScript standards. Avoid outdated or browser-specific code.

2. Test on All Major Browsers
   Regularly test your site using tools like:

   • BrowserStack

   • LambdaTest

   • Manually test on real browsers and devices when possible.

3. Use Responsive Design
   Make sure your site adjusts gracefully across different screen sizes and resolutions.

4. Avoid Proprietary Features
   Don’t rely on browser-specific functionality unless absolutely necessary—and always provide fallbacks.

5. Normalize CSS Styles
   Use a CSS reset or normalize.css to minimize browser-specific style inconsistencies.

6. Check JavaScript Compatibility
   Use polyfills or transpilers (like Babel) to support older browsers if needed.

7. Validate Your Code
   Run your HTML and CSS through validators like W3C Validator to spot and fix errors.
