# declaration-block-semicolon-space-before

> **Warning** This rule is deprecated and will be removed in the future. See [the migration guide](../../../docs/migration-guide/to-15.md).

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

<!-- prettier-ignore -->
```css
a { color: pink; }
/**            ↑
 * The space before this semicolon */
```

This rule ignores semicolons that are preceded by Less mixins.

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