## Description
<section id='description'>
Font size is controlled by the <code>font-size</code> CSS property, like this:

```css
h1 {
  font-size: 30px;
}
```

</section>

## Instructions
<section id='instructions'>
Inside the same <code>&#60;style&#62;</code> tag that contains your <code>red-text</code> class, create an entry for <code>p</code> elements and set the <code>font-size</code> to 16 pixels (<code>16px</code>).
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: Between the <code>style</code> tags, give the <code>p</code> elements <code>font-size</code> of <code>16px</code>. Browser and Text zoom should be at 100%.
    testString: assert(code.match(/p\s*{\s*font-size\s*:\s*16\s*px\s*;\s*}/i));

```
