PostCSS Logical Float And Clear

npm install @csstools/postcss-logical-float-and-clear --save-dev

PostCSS Logical Float And Clear lets you use logical, rather than physical, direction and dimension mappings in CSS, following the CSS Logical Properties and Values specification.

.element {
	clear: inline-start;
	float: inline-end;
}

/* becomes */

.element {
	clear: left;
	float: right;
}

Usage

Add PostCSS Logical Float And Clear to your project:

npm install postcss @csstools/postcss-logical-float-and-clear --save-dev

Use it as a PostCSS plugin:

const postcss = require('postcss');
const postcssLogicalFloatAndClear = require('@csstools/postcss-logical-float-and-clear');

postcss([
	postcssLogicalFloatAndClear(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);

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.

postcssLogicalFloatAndClear({
	inlineDirection: 'right-to-left'
})

.element {
	clear: inline-start;
	float: inline-end;
}

/* becomes */

.element {
	clear: right;
	float: left;
}

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 run if inlineDirection becomes vertical.
