It works on\nat rules, normal rules and declarations. Note that this module does not have any\nresponsibility for normalising declarations, selectors or whitespace, so that it\nconsiders these two rules to be different:\n\n```css\nh1, h2 {\n    color: blue;\n}\n\nh2, h1 {\n    color: blue;\n}\n```\n\nIt has to assume that your rules have already been transformed by another\nprocessor, otherwise it would be responsible for too many things.\n\n### Input\n\n```css\nh1 {\n    margin: 0 auto;\n    margin: 0 auto\n}\n\nh1 {\n    margin: 0 auto\n}\n```\n\n### Output\n\n```css\nh1 {\n    margin: 0 auto\n}\n```\n\n## Usage\n\nSee the [PostCSS documentation](https://github.com/postcss/postcss#usage) for\nexamples for your environment.\n\n\n## Contributors\n\nSee [CONTRIBUTORS.md](https://github.com/cssnano/cssnano/blob/master/CONTRIBUTORS.md).\n\n\n## License\n\nMIT © [Ben Briggs](http://beneb.info)\n\n\n[postcss]: https://github.com/postcss/postcss\n"
