# --description--

Create a rule that targets both `.one` and `.two` and increase their `blur` effect by 1 pixel.

Here's an example of a rule that increases the `blur` of two elements:

```css
h1, p {
  filter: blur(3px);
}
```

# --hints--

You should have a `.one, .two` selector.

```js
const oneTwo = new __helpers.CSSHelp(document).getStyle('.one, .two');
assert(oneTwo);
```

You should set the `filter` property to `blur(1px)`.

```js
const hasFilter = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style.filter === 'blur(1px)');
assert(hasFilter)
```

Your `.one` element should have a `filter` value of `blur(1px)`.

```js
const one = document.querySelector('.one');
const oneFilter = getComputedStyle(one).filter;
assert(oneFilter === 'blur(1px)');
```

Your `.two` element should have a filter value of `blur(1px)`.

```js
const two = document.querySelector('.two');
const twoFilter = getComputedStyle(two).filter;
assert(twoFilter === 'blur(1px)');
```
