# --description--
|
|
|
|
An element's `margin` controls the amount of space between an element's `border` and surrounding elements.
|
|
|
|
If you set an element's `margin` to a negative value, the element will grow larger.
|
|
|
|
# --instructions--
|
|
|
|
Try to set the `margin` to a negative value like the one for the red box.
|
|
|
|
Change the `margin` of the blue box to `-15px`, so it fills the entire horizontal width of the yellow box around it.
|
|
|
|
# --hints--
|
|
|
|
Your `blue-box` class should give elements `-15px` of `margin`.
|
|
|
|
```js
|
|
assert($('.blue-box').css('margin-top') === '-15px');
|
|
```
