The WordPress Style Engine generates the CSS for a block theme. Why would you want to know how an invisible process like that works? Well, just like writing CSS, you will want to ensure your code is organized and structured so that your styles properly use the CSS Cascade.

Let’s move to the other top-level section of theme.json where we can configure the CSS of a block theme: styles. We’ll learn what it is exactly and how we can use it to override and apply the preset settings values we covered in Part 2.
Let's take what we learned about the theme.json structure in WordPress block themes and apply it to two main sections of the file: settings and styles. These arrays are the “top level” for configuring WordPress features and the theme’s CSS output.
To kick things off, let’s begin by reviewing a few glossary terms that are important for understanding what the theme.json file is, how it is structured, and how to configure it.
