# selector-attribute-brackets-space-inside
Require a single space or disallow whitespace on the inside of the brackets within attribute selectors.
```css
[ target=_blank ]
/** ↑ ↑
* The space inside these two brackets */
```
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
