[] lets you easily use vb and vi length units following the [CSS-Values-4 Specification].

<example.css>

/* becomes */

<example.expect.css>

The inlineDirection option allows you to specify the direction of the inline axe. The default value is left-to-right, which would match any latin language.

You should tweak this value so that it is specific to your language and writing mode.

<exportName>({
	inlineDirection: 'top-to-bottom'
})

<example.css>

/* becomes */

<example.vertical.expect.css>

Each direction must be one of the following:

• top-to-bottom
• bottom-to-top
• left-to-right
• right-to-left

Please do note that transformations won't do anything particular for right-to-left or bottom-to-top.

The preserve option determines whether the original notation is preserved. By default, it is preserved.

<exportName>({ preserve: false })

<example.css>

/* becomes */

<example.preserve-false.expect.css>
