How can I test the responsiveness of my website?
You can test the responsiveness of your website with browser developer tools that integrate a responsive design mode. Such tools enable you to run simulations with different device sizes to see how the website responds. You can also test your website for various screen sizes on online emulators or physical devices.
Google's mobile-friendly test, BrowserStack, and Responsive Design Checker are among the tools suitable for testing social media pages for responsive design.
