remove title on home page

Please don’t use ALL CAPS BECAUSE THAT’S SHOUTING!!!!!!

I don’t see any title (even hidden by CSS) on that page. How did you hide the titles?

.home h2.entry-title {
    display: none;
}

To add CSS: use the “Additional CSS” option in the customizer. https://codex.wordpress.org/CSS#Custom_CSS_in_WordPress
