Inspecting HTTPS (TLS, SSL) certificates from the command line

I needed to inspect an HTTPS site's current certs and wanted to do it from the command line. Here are a couple of commands that I used that worked quite well.

With nmap

nmap -p 443 --script ssl-cert [hostname]

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}
