Hide page titles

I tried the custom CSS:

.page header.entry-header {
display: none;

But page titles are still appearing.

Hello Heather,

Please try to use the following CSS code to hide page (not post) titles. Please note that it will also hide titles on WooCommerce pages (if you are using it).

You can add CSS code to your site with Simple Custom CSS plugin (just copy CSS code and paste it in Dashboard → Appearance → Custom CSS after installing and activating the plugin). Also you can add CSS code directly to style.css file of your child theme.

article.page > header.entry-header {
    display: none;

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
