Overview

Class “lifted” from Markaby to store element options. Methods called against the CssProxy object are added as element classes or IDs.

Modified to accept args for empty, non-void elements, and to capture and restore indentation state.

See the README for examples.

def initialize(builder, stream, sym, args)
  @builder = builder
  @indent  = builder.indentation_state!
  @stream  = stream
  @sym     = sym
  @args    = args
  @attrs   = {}

  @original_stream_length = @stream.length

  @builder.tag! sym, *args
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(id_or_class, *args, &block) ⇒ Object (private)

Adds attributes to an element. Bang methods set the :id attribute. Other methods add to the :class attribute.
