# --description--
|
|
|
|
Also add a `box-sizing` of `border-box` to everything. This will make it so the border you added doesn't add any size to your elements.
|
|
|
|
# --hints--
|
|
|
|
You should use the `box-sizing` property.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).isPropertyUsed('box-sizing'));
|
|
```
|
|
|
|
You should make use of the existing `*` selector.
|
|
|
|
```js
|
|
// Two selectors create two CSSStyleRule objects
|
|
assert.equal(new __helpers.CSSHelp(document).getStyleDeclarations('*').length, 1);
|
|
```
|
|
|
|
All elements should have a `box-sizing` of `border-box`.
|
|
|
|
```js
|
|
const astStyles = new __helpers.CSSHelp(document).getStyle('*');
|
|
assert.equal(astStyles.boxSizing, 'border-box');
|
|
```
