Stylelint Plugin Logical CSS aims to enforce the use of logical CSS properties,
values and units. The plugin provides two rules. But first, let's get set up.

> [Read more about Logical CSS on MDN](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Logical_Properties)

## Getting Started

> Before getting started with the plugin, you must first have
> [Stylelint](https://stylelint.io/) version 14.0.0 or greater installed

To get started using the plugin, it must first be installed.

```bash
npm i stylelint-plugin-logical-css --save-dev
```

```bash
yarn add stylelint-plugin-logical-css --dev
```

With the plugin installed, the rule(s) can be added to the project's Stylelint
configuration.

```json
{
  "plugins": ["stylelint-plugin-logical-css"],
  "rules": {
    "plugin/use-logical-properties-and-values": [
      true,
      { "severity": "warning" }
    ],
    "plugin/use-logical-units": [true, { "severity": "warning" }]
  }
}
```

## Rules

- [plugin/use-logical-properties-and-values](#pluginuse-logical-properties-and-values)
- [plugin/use-logical-units](#pluginuse-logical-units)

### plugin/use-logical-properties-and-values

This rule is responsible for checking both CSS properties and values. When a
physical property or value is found, it will be flagged.

```json
{
  "rules": {
    "plugin/use-logical-properties-and-values": [
      true,
      { "severity": "warning" }
    ]
  }
}
```

#### Options

| Option           | Description                                                              |
| ---------------- | ------------------------------------------------------------------------ |
| disable-auto-fix | Use this option to prevent auto-fixing warnings and errors while saving. |
| ignore           | Pass an array of physical properties to ignore while linting.            |

```json
{
  "rules": {
    "plugin/use-logical-properties-and-values": [
      true,
      {
        "severity": "warning",
        "disable-auto-fix": true,
        "ignore": ["overflow-y", "overflow-x"]
      }
    ]
  }
}
```

#### Usage

##### Not Allowed

```css
.heading {
  max-width: 90ch; /* Will flag the use of "width" */
  text-align: left; /* Will flag the use of "left" */
  opacity: 1;
  transition: opacity 1s ease, max-width 1s ease; /* Will flag the use of 'max-width' */
}
```

##### Allowed

```css
.heading {
  max-inline-size: 90ch;
  text-align: start;
  opacity: 1;
  transition: opacity 1s ease, max-inline-size: 1s ease;
}
```

### plugin/use-logical-units

This rule is responsible for checking that logical CSS units are used.
Specifically, viewport units like `vw` and `vh` which stand for viewport width
and viewport height respectively will not reflect different writing modes and
directions. Instead, this rule will enforce the logical equivalents, `vi` and
`vb`.

```json
{
  "rules": {
    "plugin/use-logical-units": [true, { "severity": "warning" }]
  }
}
```

#### Options

| Option           | Description                                                              |
| ---------------- | ------------------------------------------------------------------------ |
| disable-auto-fix | Use this option to prevent auto-fixing warnings and errors while saving. |
| ignore           | Pass an array of physical units to ignore while linting.                 |

```json
{
  "rules": {
    "plugin/use-logical-properties-and-values": [
      true,
      {
        "severity": "warning",
        "disable-auto-fix": true,
        "ignore": ["dvh", "dvw"]
      }
    ]
  }
}
```

#### Usage

##### Not Allowed

```css
body {
  max-block-size: 100vh; /* Will flag the physical use of viewport "height" */
}
```

##### Allowed

```css
body {
  max-block-size: 100vb;
}
```

#### Supported Units
