Method: Coradoc::Element::Base#simplify_block_content

Defined in:
lib/coradoc/element/base.rb

#simplify_block_content(content) ⇒ Object

The idea here, is that HTML content generators may often introduce a lot of unnecessary markup, that only makes sense in the HTML+CSS context. The idea is that certain cases can be simplified, making it so that the result is equivalent, but much simpler, allowing us to generate a nicer AsciiDoc syntax for those cases.
