## Description
<section id='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 <code>::before</code> and <code>::after</code> pseudo-elements. These pseudo-elements are used to add something before or after a selected element. In the following example, a <code>::before</code> pseudo-element is used to add a rectangle to an element with the class <code>heart</code>:
<blockquote>.heart::before {<br>&nbsp;&nbsp;content: "";<br>&nbsp;&nbsp;background-color: yellow;<br>&nbsp;&nbsp;border-radius: 25%;<br>&nbsp;&nbsp;position: absolute;<br>&nbsp;&nbsp;height: 50px;<br>&nbsp;&nbsp;width: 70px;<br>&nbsp;&nbsp;top: -50px;<br>&nbsp;&nbsp;left: 5px;<br>}</blockquote>
For the <code>::before</code> and <code>::after</code> pseudo-elements to function properly, they must have a defined <code>content</code> property. This property is usually used to add things like a photo or text to the selected element. When the <code>::before</code> and <code>::after</code> pseudo-elements are used to make shapes, the <code>content</code> property is still required, but it's set to an empty string.
In the above example, the element with the class of <code>heart</code> has a <code>::before</code> pseudo-element that produces a yellow rectangle with <code>height</code> and <code>width</code> of 50px and 70px, respectively. This rectangle has round corners due to its 25% border radius and is positioned absolutely at 5px from the <code>left</code> and 50px above the <code>top</code> of the element.

## Instructions
<section id='instructions'>
Transform the element on the screen to a heart. In the <code>heart::after</code> selector, change the <code>background-color</code> to pink and the <code>border-radius</code> to 50%.
Next, target the element with the class <code>heart</code> (just <code>heart</code>) and fill in the <code>transform</code> property. Use the <code>rotate()</code> function with -45 degrees. (<code>rotate()</code> works the same way that <code>skewX()</code> and <code>skewY()</code> do).
Finally, in the <code>heart::before</code> selector, set its <code>content</code> property to an empty string.

## Tests
<section id='tests'>

```yml
- text: 'The <code>background-color</code> property of the <code>heart::after</code> selector should be pink.'
  testString: 'assert(code.match(/\.heart::after\s*?{\s*?background-color\s*?:\s*?pink\s*?;/gi), ''The <code>background-color</code> property of the <code>heart::after</code> selector should be pink.'');'
- text: 'The <code>border-radius</code> of the <code>heart::after</code> selector should be 50%.'
  testString: 'assert(code.match(/border-radius\s*?:\s*?50%/gi).length == 2, ''The <code>border-radius</code> of the <code>heart::after</code> selector should be 50%.'');'
- text: The <code>transform</code> property for the <code>heart</code> class should use a <code>rotate()</code> function set to -45 degrees.
  testString: 'assert(code.match(/transform\s*?:\s*?rotate\(\s*?-45deg\s*?\)/gi), ''The <code>transform</code> property for the <code>heart</code> class should use a <code>rotate()</code> function set to -45 degrees.'');'
- text: 'The <code>content</code> of the <code>heart::before</code> selector should be an empty string.'
  testString: 'assert(code.match(/\.heart::before\s*?{\s*?content\s*?:\s*?("|'')\1\s*?;/gi), ''The <code>content</code> of the <code>heart::before</code> selector should be an empty string.'');'
