  59. * Every parser saves its own properties,

  61. *
  62. * * `before`: the space symbols before the node. It also stores `*`
  63. * and `_` symbols before the declaration (IE hack).

  69. * PostCSS cleans declaration from comments and extra spaces,
  70. * but it stores origin content in raws properties.
  71. * As such, if you don’t change a declaration’s value,
  72. * PostCSS will use the raw value with comments.

  74. * @example
  75. * const root = postcss.parse('a {\n color:black\n}')
  76. * root.first.first.raws //=> { before: '\n ', between: ':' }
