# --description--

One of the most popular shapes in the world is the heart shape, and in this challenge you'll create one using pure CSS. But first, you need to understand the `::before` and `::after` pseudo-elements. These pseudo-elements are used to add something before or after a selected element. In the following example, a `::before` pseudo-element is used to add a rectangle to an element with the class `heart`:

```css
.heart::before {
  content: "";
  background-color: yellow;
  border-radius: 25%;
  position: absolute;
  height: 50px;
  width: 70px;
  top: -50px;
  left: 5px;
}
```

For the `::before` and `::after` pseudo-elements to function properly, they must have a defined `content` property. This property is usually used to add things like a photo or text to the selected element. When the `::before` and `::after` pseudo-elements are used to make shapes, the `content` property is still required, but it's set to an empty string. In the above example, the element with the class of `heart` has a `::before` pseudo-element that produces a yellow rectangle with height and width of `50px` and `70px`, respectively. This rectangle has round corners due to its 25% `border-radius` and is positioned absolutely at `5px` from the left and `50px` above the top of the element.

# --instructions--

Transform the element on the screen to a heart. In the `heart::after` selector, change the `background-color` to `pink` and the `border-radius` to 50%.

Next, target the element with the class `heart` (just `heart`) and fill in the `transform` property. Use the `rotate()` function with -45 degrees.

Finally, in the `heart::before` selector, set its `content` property to an empty string.

# --hints--

The `background-color` property of the `heart::after` selector should be `pink`.

```js
const heartAfter = code.match(/\.heart::after\s*{[\s\S]+?[^\}]}/g)[0];
assert(
  /({|;)\s*background-color\s*:\s*pink\s*(;|})/g.test(heartAfter)
);
```

The `border-radius` of the `heart::after` selector should be 50%.

```js
assert(code.match(/border-radius\s*?:\s*?50%/gi).length == 2);
```

The `transform` property for the `heart` class should use a `rotate()` function set to -45 degrees.

```js
assert(code.match(/transform\s*?:\s*?rotate\(\s*?-45deg\s*?\)/gi));
```

The `content` of the `heart::before` selector should be an empty string.

```js
assert(code.match(/\.heart::before\s*?{\s*?content\s*?:\s*?("|')\1\s*?;/gi));
```
