api
重要的说明
create node api
- postcss.atRule(props): creates a new @ node
- postcss.rule(props): creates a new rule node
- postcss.decl(props): creates a new Declaration node
- postcss.comment(props): creates a new Declaration node
- postcss.comment(props): creates a new Comment node
declaration node
var root = postcss.parse('a { color: black }');
var decl = root.first.first;
decl.type //=> 'decl'
decl.toString() //=> ' color: black'
container.walkDecls([propFilter,] callback)
遍历container下面的rule或decl,可以进行一些操作。
重要的那些api是同步api那些是异步api,为什么这些是同步api,为什么是异步的?
