Remove "leave a comment" on posts?

What is the CSS to remove "leave a comment" on posts? And it this universal with all Ink Themes?

 

Hello,

Paste the code given below in Custom CSS section
(Appearance -> Theme Options -> Styling Options -> Custom CSS) of your dashboard.

Code:

div.post-info {
display: none;
} 

This will remove "leave a comment" text from the post of Blackriders theme.
It is not necessary that it will work for our all themes.
