Setup Requirements for Sass

Sass can be used from the command line or as part of a web framework. The first step is to install the gem:

gem install sass

After you convert some CSS to Sass, you can run

sass style.scss

to compile it back to CSS. For more information on these commands, check out

sass --help

To install Sass in Rails 2, just add config.gem "sass" to config/environment.rb. In Rails 3, add gem "sass" to your Gemfile instead. .sass or .scss files should be placed in public/stylesheets/sass, where they'll be automatically compiled to corresponding CSS files in public/stylesheets when needed (the Sass template directory is customizable... see the Sass reference for details).

Sass can also be used with any Rack-enabled web framework. To do so, just add

require 'sass/plugin/rack'
use Sass::Plugin::Rack

to config.ru. Then any Sass files in public/stylesheets/sass will be compiled into CSS files in public/stylesheets on every request.

To use Sass programmatically, check out the YARD documentation.

Formatting

Sass is an extension of CSS that adds power and elegance to the basic language. It allows you to use variables, nested rules, mixins, inline imports, and more, all with a fully CSS-compatible syntax. Sass helps keep large stylesheets well-organized, and get small stylesheets up and running quickly, particularly with the help of the Compass style library.

Sass has two syntaxes. The one presented here, known as "SCSS" (for "Sassy CSS"), is fully CSS-compatible. The other (older) syntax, known as the indented syntax or just "Sass", is whitespace-sensitive and indentation-based. For more information, see the reference documentation.

To run the following examples and see the CSS they produce, put them in a file called test.scss and run sass test.scss.

Nesting

Sass avoids repetition by nesting selectors within one another. The same thing works for properties.

table.hl {
  margin: 2em 0;
  td.ln { text-align: right; }
}

li {
  font: {
    family: serif;
    weight: bold;
    size: 1.2em;
  }
}

Variables

Use the same color all over the place? Need to do some math with height and width and text size? Sass supports variables, math operations, and many useful functions.

$blue: #3bbfce;
$margin: 16px;

.content_navigation {
  border-color: $blue;
  color: darken($blue, 10%);
}

.border {
  padding: $margin / 2;
  margin: $margin / 2;
  border-color: $blue;
}

Mixins

Even more powerful than variables, mixins allow you to re-use whole chunks of CSS, properties or selectors. You can even give them arguments.

@mixin table-scaffolding {
  th {
    text-align: center;
    font-weight: bold;
  }
  td, th { padding: 2px; }
}

@mixin left($dist) {
  float: left;
  margin-left: $dist;
}

#data {
  @include left(10px);
  @include table-scaffolding;
}
