[Theme: Colorway] How to remove "One responseso far" in blogpost

And Hi again ??

I’m being busy trying to change blogpost settings. I hope you can help me with the following. Help is very much appreciated! I use Colorway Theme Lite.

(My site: https://www.mytinyhouse.nl

Right above the comment section there is this prefab false line “One Responseso far”. I know the PHP thing to change the spelling (found it here on the forum)
BUT
I would like to get rid of it entirely. Since it’s in English. And I wish to get rid of it using CSS instead of PHP (I know where to change Custom CSS, don’t know how to change PHP).

I hope you can help me with this. Thank you very much in advance!!!
