method_missing(*args, &block) click to toggle source

this is needed because the methods inside the rule blocks are actually called on the CSS object

# File lib/paggio/css.rb, line 114
def method_missing(*args, &block)
  @current.last.__send__(*args, &block)
end
rule(*names, &block) click to toggle source
# File lib/paggio/css.rb, line 64
def rule(*names, &block)
  return unless block

  if names.any? { |n| n.include? ',' }
    ::Kernel.raise ::ArgumentError, 'selectors cannot contain commas'
  end

  names.each {|name|
    @selector << name
    @current  << Rule.new(CSS.selector(@selector), @media)

    block.call

    @selector.pop
    @rules << @current.pop
  }
