# declaration-block-semicolon-space-before

Require a single space or disallow whitespace before the semicolons of declaration blocks.

```css
a { color: pink; }
/**            ↑
 * The space before this semicolon */
```

This rule ignores semicolons that are preceded by Less mixins.

The `--fix` option on the [command line](../../../docs/user-guide/cli.md#autofixing-errors) can automatically fix all of the problems reported by this rule.

## Options

```

The following patterns are *not* considered violations:

```css
a { color: pink ; }
```

```css

```
