Remove WooCommerce Headers

Hello!

I’ve built a sight using OnePress and have used the following code in the Custom CSS field to remove the headers and titles from the websites pages.

.page-id-156 .page-header {display: none;}
.page-id-156 .entry-title {display: none;}

However I cannot figure out how to do the same with the WooCommerce pages.

I’ve tried various code I’ve found through searching and none of them seem to work.

Any help you be greatly appreciated.

Thanks!
