#### options.isCssLinein
Type: Boolean
Default value: false

Whether the file currently being processed is a CSS file. Because of the CSS file and the JS file are slightly different, the comments like // in CSS is illegal and unsupported.

Setting this option to true will not handle content that exists in //.
