Class Method Details

.parse(input, options = {}) ⇒ Object

Parses input as a CSS stylesheet and returns a parse tree.

Options:

* **:maximum_depth** - Maximum nesting depth for simple blocks and
functions. Constructs nested more deeply than this are discarded to
prevent stack exhaustion. Defaults to {Parser::DEFAULT_MAXIMUM_DEPTH}.

* **:preserve_comments** - If `true`, comments will be preserved as
`:comment` tokens.

* **:preserve_hacks** - If `true`, certain non-standard browser hacks
such as the IE "*" hack will be preserved even though they violate
CSS 3 syntax rules.
