#raw_content ⇒ Object Also known as: raw_body?, raw_content?, body?

#

raw_content

This method will return the raw body of the CSS rule at hand. So if the content is ‘{ margin-left: 1em; margin-right: 1em; }’ then only the part between the two ” will returned via this method here.

Otherwise the original @result is returned.

Currently this method will remove excessive ‘ ’ too, and .strip() on the resulting String.
