Instance Method Details

#html(formatting = true) ⇒ Object

Returns the HTML text for the current object. Indentation and end tag options are optional, based on the settings of the classes themselves.

If formatting is false, then formatting and whitespace is not applied and you will get a single, very long string. Note that case is still honored.
