Requirements

postcss-values-parser Node version v6.14.0+ and PostCSS v7.0.0+.

2
3const root = parse('#fff');
4const node = root.first;
5
6// → Word {
7//     raws: { before: '', after: '' },
8//     value: '#fff',
9//     type: 'word',
10//     isHex: true,
11//     isColor: true,
12//     isVariable: false,
