changing blog post title font + navigation menu font in custom CSS

I am trying to change the blog post title fonts and navigation menu fonts in a SquareSpace 7.1 site and the normal custom code I have used in the past will not work. Below is what I have tried: 

.BlogList-item-title {

   font-family: 'my custom font name here';

 }

.Header-nav-folder-item{
  font-family: 'font name here'; }

In all other Squarespace sites I have done these codes work but for some reason it won't work with this new version. Any tips?

@nakelley SS 7.1 blog title use different class.

It should be

blog list page: h1.blog-title

blog detail page: .blog-item-title

and Navigation: .header-nav-item a

I have the same issue... successful custom CSS font change for h1 on the rest of site, but not on the blog.

The above code/answer isn't working for me. I generally don't know what I'm doing, so could easily be user error; but maybe less likely, since I did manage the rest of the site.

Ideas?

Edit: .entry-title worked for me.
