# function-comma-space-before

Require a single space or disallow whitespace before the commas of functions.

<!-- prettier-ignore -->
```css
a { transform: translate(1 ,1) }
/**                        ↑
 * The space before this comma */
```

The [`fix` option](https://stylelint.io/user-guide/options/#fix) can automatically fix all of the problems reported by this rule.

## Options

`string`: `"always"|"never"|"always-single-line"|"never-single-line"`

### `"always"`

The following patterns are considered problems:

<!-- prettier-ignore -->
```css
a { transform: translate(1,1) }
```

<!-- prettier-ignore -->
```css

```

The following patterns are _not_ considered problems:

<!-- prettier-ignore -->
```css
a { transform: translate(1 ,1) }
```

<!-- prettier-ignore -->
```css
a { transform: translate(1 , 1) }
```

### `"never"`

There _must never_ be whitespace before the commas.

The following patterns are considered problems:

<!-- prettier-ignore -->
```css
a { transform: translate(1 ,1) }
```

<!-- prettier-ignore -->
```css
a { transform: translate(1 , 1) }
```

The following patterns are _not_ considered problems:
