# --description--
元素的 `margin外边距` 用来控制元素 `border边框` 与其周围元素之间的距离大小。
如果你把元素的 `margin` 设置为负值,元素会变得占用更多空间。
# --instructions--
请将蓝色框的 `margin` 设为负值,跟红色框 `margin` 的属性值设置成一样的大小。
将蓝色框的 `margin` 设置为 `-15px`,它会让蓝色框填满整个黄色框。
# --hints--
class 为 `blue-box` 的元素的 `margin` 应设置为 `-15px`
```js
assert($('.blue-box').css('margin-top') === '-15px');
```
