// An example of how you can use it with your components

const SomeDiv = styled.div`
  ${borderProps}
  ${marginProps}
`

// This lets you pass all borderProps to the component like so:

<SomeDiv borderTop borderBottom borderLeft borderRight marginVertical>

Where is the css template function coming from? Also you're only passing in the booleans to the tag at the end (eg borderTop) but the CSS expects a borderWidth prop too... Is there a default for that somewhere.

Same question as Joe. How are you specifying the size of the border. I know there is a default set, but how would u specify a specific amount. Thanks.

Hey Joezimjs, the css template function is coming from styled-components.
import { css } from 'styled-components';
