In what scenarios is it more practical to use CSS over PHP for responsive design on a website?

In scenarios where the responsive design changes are purely visual and do not require server-side processing, it is more practical to use CSS over PHP. CSS can handle responsive design elements such as media queries, flexbox, and grid layouts efficiently without the need for server-side processing. This approach ensures faster loading times and smoother user experience on the website.
