## Description
<section id='description'>
Sass allows <code>nesting</code> of CSS rules, which is a useful way of organizing a style sheet.
Normally, each element is targeted on a different line to style it, like so:

```scss
nav {
  background-color: red;
}

nav ul {
  list-style: none;
}

nav ul li {
  display: inline-block;
}
```

For a large project, the CSS file will have many lines and rules. This is where <code>nesting</code> can help organize your code by placing child style rules within the respective parent elements:

```scss
nav {
  background-color: red;

  ul {
    list-style: none;

    li {
      display: inline-block;
    }
  }
}

```

## Instructions
<section id='instructions'>
Use the <code>nesting</code> technique shown above to re-organize the CSS rules for both children of <code>.blog-post</code> element. For testing purposes, the <code>h1</code> should come before the <code>p</code> element.
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: Your code should re-organize the CSS rules so the <code>h1</code> and <code>p</code> are nested in the <code>.blog-post</code> parent element.
    testString: assert(code.match(/\.blog-post\s*?{\s*?h1\s*?{\s*?text-align:\s*?center;\s*?color:\s*?blue;\s*?}\s*?p\s*?{\s*?font-size:\s*?20px;\s*?}\s*?}/gi));

```
