+##### options.ignore ⇒ RegExp | [RegExp,...]
+
+Takes either a single or an array of regular expressions to match against. 
+
+All matching blocks are ignored, as well as any comment-like content inside them.
+
+For example, CSS may contain Base64-encoded strings with comment-like symbols:
+```css
+  src: url(data:font/woff;base64,d09GRg//ABAAAAAAZ)
+```
+And you can isolate all `url(*)` blocks by using:
