Remove Category Title

Hi,

I have two different category pages for posts on my website:

http://yogashalawest.com/category/blog/
http://yogashalawest.com/category/events/

Can anyone tell me what to add to my Jetpack CSS Stylesheet Editor to make the titles on those pages disappear? To clarify, I’d like to remove ‘Blog’ and ‘Events’ from each of the respective pages.

I’ve tried looking through previous threads and nothing has worked.

Thank you!
