WordPress 5.0 introduces the new block-based post editor. This is the first step toward an exciting new future with a streamlined editing experience across your site. You’ll have more flexibility with how content is displayed, whether you are building your first site, revamping your blog, or write code for a living.

Whether you’re running a photo blog, launching a new business, or supporting a non-profit, Twenty Nineteen is flexible enough to fit your needs.
