I am not a fan of navigations that overflow on small devices (since I have to use a larger line height to make them jump to the next line). Also, some spans being inside the <a> tag made styling them a bit problematic. I use simple pagination with previous, current and next post features. But I will revisit the internal pagination within a week once I have my test site up and running on Cloudflare pages. I also found this issue which I am unsure if it was resolved.
