pugやらsassやら、名称がイマイチ好きになれんなーと思いつつ、
sassを入れます。

[vagrant@localhost python]$ gem install sass

数秒待つと、、、
入りました！
[vagrant@localhost python]$ sass –version
Ruby Sass 3.5.7

style.sass

body
	background-color: lightgray

コンパイルします。
[vagrant@localhost python]$ sass css/style.sass:css/style.css

おおおおおおおおおおおおおお、
出来とる！

それで、、、
style.css

body {
  background-color: lightgray; }

[vagrant@localhost sass]$ compass -v

*********************************************************************
Congratulations! Your compass project has been created.

You may now add and edit sass stylesheets in the sass subdirectory of your project.

Sass files beginning with an underscore are called partials and won't be
compiled to CSS, but they can be imported into other sass stylesheets.

You can configure your project by editing the config.rb configuration file.

You must compile your sass stylesheets into CSS when they change.
This can be done in one of the following ways:
  1. To compile on demand:
     compass compile [path/to/project]
  2. To monitor your project for changes and automatically recompile:
     compass watch [path/to/project]

gemでsassをインストールします。

[vagrant@localhost ~]$ sudo gem install sass
Successfully installed sass-3.4.22

sass記法でcssを記載していきます。

#main {
  width: 90%;
  p {
    font-size: 14px;
  }
}

sassコマンドで、main.cssに変換します。

sass --style expanded scss/main.scss:css/main.css

変換結果です。

#main {
  width: 90%;
}
#main p {
  font-size: 14px;
}

sassからcssへの自動変換コマンド

[vagrant@localhost sass]$ sass --style expanded --watch scss:css
>>> Sass is watching for changes. Press Ctrl-C to stop.
>>> Change detected to: scss/main.scss
      write css/main.css
      write css/main.css.map

scssの特徴である入れ子構造

#main {
  width: 90%;
  p {
    font-size: 18px;
    a {
      text-decoration: none;
      &:hover {
        font-weight: bold;
      }
    }
  }
}

変数

$baseFontSize: 14px;

#main {
  width: 90%;
  p {
    font-size: $baseFontSize;
    .sub {
      font-size: $baseFontSize - 2px;
    }
  }
}

文字列

$imgDir: "../img/";

#main {
  width: 90%;
  background: url($imgDir + "bg.png");
  p {
    font-size: $baseFontSize;
    
  }
}
