Options

#### prefix

The prefix option defines a prefix required by properties being transformed.
Wrapping dashes are automatically applied, so that x would transform
-x-border-top-radius.

`js
postcssShortBorderRadius({ prefix: 'x' });
`

`pcss
.example-1 {
-x-border-top-radius: 10px;
}

/ becomes /

.example-1 {
border-top-left-radius: 10px;
border-top-right-radius: 10px;
}
`

#### skip

The skip option defines the skip token used to ignore portions of the
shorthand.

`js
postcssShortBorderRadius({ skip: '-' });
`

`pcss
.example-1 {
-x-border-top-radius: - 10px;
}

/ becomes /

.example-1 {
border-top-right-radius: 10px;
}
