Removing page titles

Hi! I want to remove the big page titles that appear on top of my image headers on each page, but when I paste this

.page #header .bottom-header h2{
display: none;
}

into Dashboard > Appearances > Editor > Style.css, nothing happens. Per your suggestion, I also tried it in Appearance > Customize > Additional CSS with no result as well. What am I doing wrong? My site is http://www.meowornever.org

Thank you!

Oops, sorry. It did duplicate my post and I can’t figure out how to remove one!

Hello there,

I hope you are doing well today.

I will go ahead and close this post.

Best Regards,
