|
||
*
|
||
* 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.
|
||
* * `afterName`: the space between the at-rule name and its parameters.
|
||
*
|
||
* PostCSS cleans at-rule parameters 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(' @media\nprint {\n}')
|
||
* root.first.first.raws //=> { before: ' ',
