How to hide meta-bar on Travelify WordPress template?

I’d like to hide meta-bar(author,date,category,comment).
How can I edit php?

You can hide meta information that you can see on this theme including author name, date and category by adding this simple CSS to Appearance >> Theme Options >> Other >> Custom CSS

.entry-meta {
  display: none;
