  "readme": "# PostCSS Discard Overridden\n\n[PostCSS] plugin to discard overridden `@keyframes` or `@counter-style`.\n\n`@keyframes` or `@counter-style` will be overridden by those who share the same identifiers and appear later in stylesheets. So we can discard all of them except the last one. When defined inside a `@media` or `@supports` rule, `@keyframes` and `@counter-style` rules only override global rules in some of the client browsers so they need handled separately. This plugin has taken care of this and transforms the PostCss AST **safely**.\n\n[PostCSS]: https://github.com/postcss/postcss\n\n```css\n@-webkit-keyframes fade-in {\n  0% {\n    opacity: 0;\n  }\n  100% {\n    opacity: 0.8;\n  }\n}\n@keyframes fade-in {\n  0% {\n    opacity: 0;\n  }\n  100% {\n    opacity: 0.8;\n  }\n}\n@media (max-width: 500px) {\n  @-webkit-keyframes fade-in {\n    0% {\n      opacity: 0;\n    }\n    100% {\n      opacity: 1;\n    }\n  }\n  @keyframes fade-in {\n    0% {\n      opacity: 0;\n    }\n    100% {\n      opacity: 1;\n    }\n  }\n  @-webkit-keyframes fade-in {\n    0% {\n      opacity: 0;\n    }\n    100% {\n      opacity: 0.8;\n    }\n  }\n  @keyframes fade-in {\n    0% {\n      opacity: 0;\n    }\n    100% {\n      opacity: 0.8;\n    }\n  }\n  @supports (display: flex) {\n    @-webkit-keyframes fade-in {\n      0% {\n        opacity: 0;\n      }\n      100% {\n        opacity: 1;\n      }\n    }\n    @keyframes fade-in {\n      0% {\n        opacity: 0;\n      }\n      100% {\n        opacity: 1;\n      }\n    }\n  }\n}\n@-webkit-keyframes fade-in {\n  0% {\n    opacity: 0;\n  }\n  100% {\n    opacity: 1;\n  }\n}\n@keyframes fade-in {\n  0% {\n    opacity: 0;\n  }\n  100% {\n    opacity: 1;\n  }\n}\n```\n\n```css\n@media (max-width: 500px) {\n  @-webkit-keyframes fade-in {\n    0% {\n      opacity: 0;\n    }\n    100% {\n      opacity: 0.8;\n    }\n  }\n  @keyframes fade-in {\n    0% {\n      opacity: 0;\n    }\n    100% {\n      opacity: 0.8;\n    }\n  }\n  @supports (display: flex) {\n    @-webkit-keyframes fade-in {\n      0% {\n        opacity: 0;\n      }\n      100% {\n        opacity: 1;\n      }\n    }\n    @keyframes fade-in {\n      0% {\n        opacity: 0;\n      }\n      100% {\n        opacity: 1;\n      }\n    }\n  }\n}\n@-webkit-keyframes fade-in {\n  0% {\n    opacity: 0;\n  }\n  100% {\n    opacity: 1;\n  }\n}\n@keyframes fade-in {\n  0% {\n    opacity: 0;\n  }\n  100% {\n    opacity: 1;\n  }\n}\n```\n\n## Usage\n\nSee the [PostCSS documentation](https://github.com/postcss/postcss#usage) for\nexamples for your environment.\n\n## Contributors\n\nSee [CONTRIBUTORS.md](https://github.com/cssnano/cssnano/blob/master/CONTRIBUTORS.md).\n"
