Hiding Author Name, Comments count in Block 3

I’ve added a block 3 element below the author box referring this forum post https://forum.tagdiv.com/topic/is-is-possible-to-create-this-element/. The element has been added. I want to hide the author name, post comment count displayed by the article. But i’m not able to do so. I’ve tried this with the below codes, but the code doesn’t work.

.td_block_3 .td-post-author-name .td-module-comments
{
display: none!important;
}

.custom-block3 .td-post-author-name .td-module-comments
{
display: none!important;
}

How to add the author name, comment count with the CSS?

problem has been fixed!
