Cannot hide site title

I am trying to hide a site title on dekalbdems.com from every page.

There is nothing within the theme to check to make it not show, so I have tried various CSS to make it hide. That is not working either.

I have tried to add the following into the custom CSS portion, but it won’t make the title go away.

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

What am I missing?

The blog I need help with is dekalbdems.com.
