How to hide posted by, post date etc only from selected posts not from all?

What is the criteria that meets “selected posts”? Is it a type of post or could be any type?

Any type of normal posts. I just want to hide these meta post data from one single post of my site not from all posts. I think there would be a custom css with my wanted post id but I can’t write it accurately.

Again @graphical_force for making it more clear. I have other posts in the site but i want to hide these post data just from this post

https://onlinecontestfinder.com/another-test-votes.html

This is post it may be 51.

So there has to be a way to identify these types of posts. So are you saying you want to hide these on all single posts?

Only from this post https://onlinecontestfinder.com/another-test-votes.html not from all other single posts of the site. I know there has to be a way but don’t know the exact way. Do you know?

Try this in your css:

#post-51 .byline {
  display: none;
}

make sure that you put your edits in a child theme so you don’t lose them when you update your theme: https://codex.www.ads-software.com/Child_Themes

Thanks a lot graphical_force. It worked.

No problem!
