Using uBlock Origin, how do I block a root site without blocking sub-pages?

I am getting really distracted by YouTube recently, but I still need access to YouTube videos. I inadvertently visit youtube.com, and I would like to block this page without blocking the whole site. Is there a uBlock filter that only works on the root page?

Is there a [uBlock Origin] filter that only works on the root page?

Yes, use the document filter option:

||youtube.com^|$document 

With Squid Cache Rule:

acl whitedomains dstdomain -i "/path_to_acl/whitedomains.txt" acl blackdomains dstdomain -i "/path_to_acl/blackdomains.txt" http_access allow whitedomains http_access deny blackdomains 

Content of the lists:

/path_to_acl/whitedomains.txt .account.youtube.com .google.com /path_to_acl/blackdomains.txt .youtube.com .googlevideo.com .ytimg.com 

PD: Since February 2014, Google uses the accounts subdomain .youtube.com to authenticate their services.
