 The Sass syntax has several useful extensions to CSS. One of them is the parent selector shortcut: &. We can use & in our style definition of a selector and Sass will replace it with the parent selector of the rules when the code is converted to CSS. If we use the parent selector (&) in nested rules the complete parent selector is first resolved and then used to replace &.

h1 {
    padding: 20px 0 10px 0;

    // & will be replaced with parent selector h1.
    &.pageHeader {
        color: #f7f7f7;
    }

    // & will be replaced with parent selector h1.
    body.main & {
        color: #ccc;
    }
}

// Parent selector can have a class or id.
a.first {
    text-decoration: none;

    // Parent selector works on pseudo-classes as well.
    &:hover {
        text-decoration: underline;
    }
}

body {
    .article {
        h1 {
            color: #7f7f7f;

            // In nested rules the parent selector is 
            // completely resolved before being used.
            // The complete parent selector here is
            // body .article h1.
            &.blog {
                font-weight: bold;
            }
        }

    }
}

The resulting CSS is in the following sample:

h1 {
  padding: 20px 0 10px 0;
}
h1.pageHeader {
  color: #f7f7f7;
}
body.main h1 {
  color: #ccc;
}

a.first {
  text-decoration: none;
}
a.first:hover {
  text-decoration: underline;
}

body .article h1 {
  color: #7f7f7f;
}
body .article h1.blog {
  font-weight: bold;
}
