source: the path to the file containing css. Makes errors and source
maps more helpful, by letting them know where code comes from.
css.stringify(object, [options])
Accepts an AST object (as css.parse produces) and returns a CSS string.
options:
indent: the string used to indent the output. Defaults to two spaces.
compress: omit comments and extraneous whitespace.
sourcemap: return a sourcemap along with the CSS output. Using the source
option of css.parse is strongly recommended when creating a source map.
Specify sourcemap: 'generator' to return the SourceMapGenerator object
instead of serializing the source map.
inputSourcemaps: (enabled by default, specify false to disable) reads any
source maps referenced by the input files when generating the output source
map. When enabled, file system access may be required for reading the
referenced source maps.
Information about the position in the source string that corresponds to
the node.
