csslint.net doesn't support SSL

[optimalisatie]

Hi!

First of all thanks a lot for providing a great tool for enhancing CSS quality and performance!

I wanted to report that https://www.csslint.net/ is showing a SSL error.

I find this problem alike.

Solution is easy: go to http://www.csslint.net/ instead. It doesn't have ssl yet.

If there is access to the web server it would be possible to use the free Let's Encrypt SSL certificate service.

https://letsencrypt.org/

The certbot tool will automatically renew certificates.

To create a certificate:

certbot certonly -a webroot --webroot-path=/home/csslint.net/httpdocs -d csslint.net -d www.csslint.net

To allow certificate verification in Nginx:

# lets encrypt
location ^~ /.well-known/ {
	default_type "text/plain";
	allow all;
	try_files $uri =404;
}
