# --description--
The windows are stacked on top of each other at the left of the section, behind the purple building. Add a new class below `.building-wrap` called `.window-wrap`, and add these properties to it:
```css
display: flex;
align-items: center;
justify-content: space-evenly;
```
This will be used in a few places to center window elements vertically, and evenly space them in their parent.
# --hints--
You should create a `.window-wrap` selector.
```js
assert.exists(new __helpers.CSSHelp(document).getStyle(".window-wrap"));
```
You should give `.window-wrap` a `display` of `flex`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle(".window-wrap")?.display, "flex");
```
You should give `.window-wrap` an `align-items` of `center`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle(".window-wrap")?.alignItems, "center");
```
You should give `.window-wrap` a `justify-content` of `space-evenly`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle(".window-wrap")?.justifyContent, "space-evenly");
```
