# Haml blocks (and ERB blocks, for that matter) don't return their contents as a string.
# They append content directly to the template.
# Thus, you need to use #capture to get their content.
# I'm not sure why this worked with ERB; it's probably just an odd consequence of an implementation detail.

# Method

  def submit(*args, &block)
    @template.content_tag(:div, :class => "save_actions") do
      super(*args) + @template.capture(&block)

/* adaptation of The 1KB CSS Grid to sass (http://www.1kbgrid.com/). I love Sass.

  @import 1kbgrid.sass
  +1kbgrid(12, 60px, 10px)

=1kbgrid(!num_columns = 12, !column_width = 60px, !gutter = 10px)
  // calculated values
  !gutter_margin = !gutter / 2

There's a couple of problems:

1. I can't modify JQuery UI's CSS file to create the mixin. Therefore it seems that SASS syntax is a no go. This is what drove me toward lesscss.
2. In less, the class must exist within the same file as where the mixin is used. In other words, the only way to make this work was to @import the JQuery UI theme into the base.css file. This is not an option, as one of the objectives is to allow the user to select a theme dynamically (for example: using http://jqueryui.com/docs/Theming/ThemeSwitcher)

Sass will support cross-file selectors-as-mixins soon, as well as some sort of syntax that is as CSS-compatible as possible. For now, though, I don't see a great solution... your best bet, if you wanted to spend some effort, would probably be to hack something together with css2sass.
