#{}

Interpolation: #{}

You can also use SassScript variables in selectors and property names using #{} interpolation syntax:

$name: foo;
$attr: border;
p.#{$name} {
  #{$attr}-color: blue;
}

is compiled to:

p.foo {
  border-color: blue; }

It’s also possible to use #{} to put SassScript into property values. In most cases this isn’t any better than using a variable, but using #{} does mean that any operations near it will be treated as plain CSS. For example:

p {
  $font-size: 12px;
  $line-height: 30px;
  font: #{$font-size}/#{$line-height};
}

is compiled to:

p {
  font: 12px/30px; }
