# NESTING

When writing HTML you've probably noticed that it has a clear nested and visual hierarchy. CSS, on the other hand, doesn't. Here's an example of some typical styles for a site's navigation:

```scss
nav {
  ul {
    margin: 0;
    padding: 0;
    list-style: none;
  }

  li { display: inline-block; }

  a {
    display: block;
    padding: 6px 12px;
    text-decoration: none;
  }
}
```

You'll notice that the ul, li, and a selectors are nested inside the nav selector. This is a great way to organize your CSS and make it more readable. When you generate the CSS you'll get something like this:

```css
nav ul {
  margin: 0;
  padding: 0;
  list-style: none;
}

nav li {
  display: inline-block;
}

nav a {
  display: block;
  padding: 6px 12px;
  text-decoration: none;
}
```

# EXERCISE

Write a stylesheet that sets `margin: 0` to the `ul`, and color of links to `red` for elements contained within an `aside` element, using nesting.
