PostCSS Logical Overflow runs in all Node environments, with special instructions for:

• Node

Options

inlineDirection

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.

postcssLogicalOverflow({
	inlineDirection: 'top-to-bottom'
})

.inline {
	overflow-inline: clip;
}

.block {
	overflow-block: scroll;
}

/* becomes */

.inline {
	overflow-y: clip;
}

.block {
	overflow-x: scroll;
}

Each direction must be one of the following:

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