How to delete this Element?

lichency

I want to remove this element on my category page.

I only know about editing custom CSS STYLE (like changing font size). But this seems nothing to do with STYLE.

I'm very new to WordPress. Please tell me is there any easy way out? Or should I find expert to help me?

I solved it by adding a new Custom CSS (line 7-9) and put display: none inside.
