Nested properties

Nested Properties

CSS has quite a few properties that are in “namespaces;” for instance, font-family, font-size, and font-weight are all in the font namespace. In CSS, if you want to set a bunch of properties in the same namespace, you have to type it out each time. Sass provides a shortcut for this: just write the namespace once, then nest each of the sub-properties within it. For example:

.funky {
  font: {
    family: fantasy;
    size: 30em;
    weight: bold;
  }
}

is compiled to:

.funky {
  font-family: fantasy;
  font-size: 30em;
  font-weight: bold; }

The property namespace itself can also have a value. For example:

.funky {
  font: 20px/24px fantasy {
    weight: bold;
  }
}

is compiled to:

.funky {
  font: 20px/24px fantasy;
    font-weight: bold;
}
