Description

Sass allows nesting 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:

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 nesting can help organize your code by placing child style rules within the respective parent elements:

nav {
  background-color: red;

  ul {
    list-style: none;

    li {
      display: inline-block;
    }
  }
}

Instructions

Use the nesting technique shown above to re-organize the CSS rules for both children of .blog-post element. For testing purposes, the h1 should come before the p element.

Tests

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));
