+Significantly expanded styling capabilities to cover more of the features that are heavily relied upon by web engineers. Styles are used with the `css.create()` function and are passed to the `style` prop on elements.
 
 ## `css()` function
 
 Styles must be wrapped in `css()`.
 
 ```js
-<div style={css({ width: 100, color: props.color })} />

-A function that returns native props, e.g., `const nativeProps = css.apply(...styles)`. On web, this is used to generate DOM `className` and `style` props, whereas on native it can be used to pass flattened/transformed styles and any other other native props to custom native components.
