Why We Wrote this Theme

We have been super excited about full-site editing capability in WordPress and have been actively working on this theme since it was in the early beta periods and finally released in WordPress v5.9. We wanted a modern replacement to our Flat Bootstrap theme that would have similar features while using only the core WordPress block editor. This theme focuses on a large flat color palettes with full-width colored sections that offer tons of block patterns and headers, footers, and blog layouts. 

We developed this theme to be unique in these key ways:

  1. It is based on the WordPress core theme Twenty Twenty Three, so you are already familiar with the technology or will learn it in a standard way that applies to many other themes.
  2. It is designed to be a modern, “flat” style theme with full-width colored sections and full-width images. This really brings your content alive and allows the reader to focus on that content instead of the theme itself.
  3. It is open source and completely free even though it offers many features common in “premium” (paid) themes.
