### combinator-space
168+
169+
Available values:
170+
* `{Boolean}`: `true` sets one space, `false` removes the spaces.
171+
* `{String}`: any combination of whitespaces.
172+
* `{Array}` with two `{String}` values: for setting left and right whitespace.
173+
174+
Example: `{ "combinator-space": true }`
175+
176+
```css
177+
/* before */
178+
a>b { color: red }
179+
180+
/* after */
181+
a > b { color: red }
182+
```
183+
184+
Example: `{ "combinator-space": "" }`
185+
186+
```css
187+
/* before */
188+
a > b { color: red }
189+
190+
/* after */
191+
a>b { color: red }
192+
```
193+

Example: `{ "combinator-space": [" ", "\n"] }`
