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

```pcss
.banner {
  color: #222222;
  inset: logical 0 5px 10px;
  padding-inline: 20px 40px;
  resize: block;
  transition: color 200ms;
}

/* becomes */

.banner:dir(ltr) {
  padding-left: 20px;
  padding-right: 40px;
}
.banner:dir(rtl) {
  padding-right: 20px;
  padding-left: 40px;
}
.banner {
  color: #222222;
  top: 0;
  left: 5px;
  bottom: 10px;
  right: 5px;
  resize: vertical;
  transition: color 200ms;
}

/* or, when used with { dir: 'ltr' } */

.banner {
  color: #222222;
  top: 0;
  left: 5px;
  bottom: 10px;
  right: 5px;
  padding-left: 20px;
  padding-right: 40px;
  resize: vertical;
  transition: color 200ms;
}

/* or, when used with { preserve: true } */

.banner:dir(ltr) {
  padding-left: 20px;
  padding-right: 40px;
}
.banner:dir(rtl) {
  padding-right: 20px;
  padding-left: 40px;
}
.banner {
  color: #222222;
  top: 0;
  left: 5px;
  bottom: 10px;
  right: 5px;
  inset: logical 0 5px 10px;
  padding-inline: 20px 40px;
  resize: vertical;
  resize: block;
  transition: color 200ms;
}
```

These shorthand properties set values for physical properties by default.
Specifying the `logical` keyboard at the beginning of the property value will
transform the flow-relative values afterward into both physical LTR and RTL
properties:

#### Logical Borders

- `border`, `border-block`, `border-block-start`, `border-block-end`,
  `border-inline`, `border-inline-start`, `border-inline-end`, `border-start`,
  `border-end`, `border-color`, `border-block-color`,
  `border-block-start-color`, `border-block-end-color`, `border-inline-color`,
  `border-inline-start-color`, `border-inline-end-color`, `border-start-color`,
  `border-end-color`, `border-style`, `border-block-style`,
  `border-block-start-style`, `border-block-end-style`, `border-inline-style`,
  `border-inline-start-style`, `border-inline-end-style`, `border-start-style`,
  `border-end-style`, `border-width`, `border-block-width`,
  `border-block-start-width`, `border-block-end-width`, `border-inline-width`,
  `border-inline-start-width`, `border-inline-end-width`, `border-start-width`,
  `border-end-width`, `border-start-start-radius`, `border-start-end-radius`,
  `border-end-start-radius`, `border-end-end-radius`

#### Logical Offsets

- `inset`, `inset-block`, `inset-block-start`, `inset-block-end`,
  `inset-inline`, `inset-inline-start`, `inset-inline-end`, `inset-start`,
  `inset-end`

#### Logical Margins

- `margin`, `margin-block`, `margin-block-start`, `margin-block-end`,
  `margin-inline`, `margin-inline-start`, `margin-inline-end`, `margin-start`,
  `margin-end`

#### Logical Paddings

- `padding`, `padding-block`, `padding-block-start`, `padding-block-end`,
  `padding-inline`, `padding-inline-start`, `padding-inline-end`,
  `padding-start`, `padding-end`

#### Logical Sizes

- `block-size`, `max-block-size`, `min-block-size`, `inline-size`, `max-inline-size`, `min-inline-size`

#### Flow-Relative Values

- `clear: inline-start`, `clear: inline-end`, `float: inline-start`,
  `float: inline-end`, `text-align: start`, `text-align: end`

By default, [PostCSS Logical Properties and Values] creates fallback selectors
which require at least one `[dir]` attribute in your HTML. If you don’t have
any `[dir]` attributes, consider using the following JavaScript:

```js
// force at least one dir attribute (this can run at any time)
document.documentElement.dir = document.documentElement.dir || 'ltr';
```

Otherwise, consider using the `dir` option to transform all logical properties
and values to a specific direction.

```js
require('postcss-logical')({
  dir: 'ltr'
});
```

## Usage

Add [PostCSS Logical Properties and Values] to your project:

```bash
npm install postcss-logical --save-dev
```

Use [PostCSS Logical Properties and Values] as a [PostCSS] plugin:

```js
const postcss = require('postcss');
const postcssLogical = require('postcss-logical');

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

[PostCSS Logical Properties and Values] runs in all Node environments, with
special instructions for:

| [Node](INSTALL.md#node) | [PostCSS CLI](INSTALL.md#postcss-cli) | [Webpack](INSTALL.md#webpack) | [Create React App](INSTALL.md#create-react-app) | [Gulp](INSTALL.md#gulp) | [Grunt](INSTALL.md#grunt) |

## Options

### dir

The `dir` option determines how directional fallbacks should be added to CSS.
By default, fallbacks replace the logical declaration with nested `:dir`
pseudo-classes. If `dir` is defined as `ltr` or `rtl` then only the left or
right directional fallbacks will replace the logical declarations. If
`preserve` is defined as `true`, then the `dir` option will be ignored.

### preserve

The `preserve` option determines whether directional fallbacks should be added
before logical declarations without replacing them. By default, directional
fallbacks replace logical declaration. If `preserve` is defined as `true`, then
the `dir` option will be ignored.

## :dir() pseudo class

This plugin transforms using the `:dir(ltr)` pseudo class.
Use [postcss-dir-pseudo-class](https://github.com/csstools/postcss-plugins/tree/main/plugins/postcss-dir-pseudo-class#readme) to further transform to `[dir="ltr"]`.

Currently `:dir(ltr)` doesn't have great browser support but this will improve over time.
