Shorthands

In CSS we can write a short notation:

```css
border: 1px solid red;
```

Which is in a full form:
```css
border-width: 1px;
border-style: solid;
border-color: red;
```

While shorthand is practical, it is not [typable](https://github.com/cssinjs/standard/issues/7) and not supported by react-native.

Should we find a replacement or even remove a support for this from this standard?

Start by reading the shorthand examples in this issue and the linked cssinjs/standard issue #7. Determine whether the specification should replace or remove shorthand notation, and consider the work complete when the project has a decided direction and the relevant specification text reflects it.
