How do I remove page title/header? In Drupal 8, is there an easy way to configure a page so that its page header/title is not displayed on the page?

I have created a Basic Page, with /home as path alias, and Home as title. I set it as front page.  However, it displays 'Home' at the top of the page, just below the navbar and breadcrumbs.

Is it necessary to create a subtheme of the 'Bootstrap' theme, and somehow add custom CSS?
Drupal 8 places the page title in its own block (called Page title). You can control when and where that block displays on the block layout page: /admin/structure/block
