|

|
|
*
|

|
|
* Every parser saves its own properties,
|
|||
|
|
* but the default CSS parser uses:
|
|||
|
|
*
|
|||
|
|
* * `before`: the space symbols before the node. It also stores `*`
|
|||
|
|
* and `_` symbols before the declaration (IE hack).
|
|||
|
|
* * `after`: the space symbols after the last child of the node
|
|||
|
|
* to the end of the node.
|
|||
|
|
* * `between`: the symbols between the property and value
|
|||
|
|
* for declarations, selector and `{` for rules, or last parameter
|
|||
|
|
* and `{` for at-rules.
|
|||
|
|
* * `semicolon`: contains true if the last child has
|
|||
|
|
* an (optional) semicolon.
|
|||
|
|
*
|
|||
|
|
* PostCSS cleans selectors from comments and extra spaces,
|
|||
|
|
* but it stores origin content in raws properties.
|
|||
|
|
* As such, if you don’t change a declaration’s value,
|
|||
|
|
* PostCSS will use the raw value with comments.
|
|||
|
|
*
|
|||
|
|
* @example
|
|||
|
|
* const root = postcss.parse('a {\n color:black\n}')
|
|||
|
|
* root.first.first.raws //=> { before: '', between: ' ', after: '\n' }
