To make your WordPress site mobile responsive, there are several steps you can take.
First, choose the best responsive WordPress theme that is designed to be responsive, as these themes will automatically adjust the layout of your site to different screen sizes. There are multiple-page templates that you can choose from.
Second, optimize your images and other media for mobile-capable devices by compressing them and reducing their file sizes.
Third, make sure your site's typography and text sizes are legible on mobile screens.
Fourth, use plugins that are compatible with mobile and optimize your site's performance by minimizing plugins and reducing page load times.
Finally, test your site on multiple devices and browsers to ensure that it looks and functions well on all platforms. By taking these steps, you can make sure that your WordPress site is mobile responsive and accessible to a wider audience.
