PostCSS Discard Overridden

PostCSS plugin to discard overridden @keyframes or @counter-style.

@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.
