Then, in your layout, output env['rack.body_classes'] in your <body> tag's class attribute.

Here's a trivial layout file, formatted with the slim templating engine, to give you an example:

html
  head
  body class="#{env['rack.body_classes']}"
    == yield

When rendered, the body tag will look something like this:

<body class="desktop chrome modern mac webkit">
