# declaration-block-semicolon-space-after

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

```css
a { color: pink; top: 0; }
/**            ↑
 * The space after this semicolon */
```

This rule ignores:

-   semicolons that are preceded by Less mixins
-   the last semicolon of declaration blocks

Use the `block-closing-brace-*-before` rules to control the whitespace between the last semicolon and the closing brace instead.

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.
