This chapter introduced you to styles in React Native. Though you can use many of the same CSS style properties that you're used to, the CSS stylesheets used in web applications look very different. Namely, they're composed of plain JavaScript objects.
Then, you learned how to work with the main React Native layout mechanism—the flexbox. This is the preferred way to layout most web applications these days, and so it only makes sense to be able to reuse this approach in a native app. You created several different layouts, and you saw how they looked in portrait and in landscape orientation.
In the following chapter, you'll start implementing navigation for your app.
