# --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: `display: flex;`, `align-items: center;`, and `justify-content: space-evenly;`. This will be used in a few places to center window elements vertically and space them evenly in their parent.
# --hints--
test-text
```js
const wWrap = code.match(/\.window-wrap\s*{[\s\S]+?[^}]}/g)[0];
assert(
/display\s*:\s*flex\s*(;|})/g.test(wWrap) &&
/align-items\s*:\s*center\s*(;|})/g.test(wWrap) &&
/justify-content\s*:\s*space-evenly\s*(;|})/g.test(wWrap)
);
```
