No date, no adm, no comments

Its possible not display the autor, the date and the comment notice on all the posts?

Hi @dagobertocosta,

I hope you are well today and thank you for your question.

You can try achieving this by adding the following CSS code in the Custom CSS option of the latest version of Sparkling theme on the below path.

Admin Area -> Appearance -> Customize -> Sparkling Options -> Other -> Custom CSS

.entry-meta span.posted-on,
.entry-meta span.byline,
.entry-meta span.comments-link {
    display: none;

Best Regards,
