Maintenance Social Media Links

Hello,

I have already viewed a previous topic regarding removal of social media links from the maintenance page of a Highend website. It was suggested to use the following code:
#hb-maintenance ul.social-list { display: none; }.

However, after inserting this code, I am given the error “Element (ul.social-list) is overqualified, just use .social-list without element name”. I tried as it suggested, and to no avail, the page still shows the links.

In addition, I wouldn’t want to get rid of all the links. I would still want Facebook available. How would I do this, let alone get this code to work?
