+# [postcss][postcss]-merge-idents
+
+> Merge keyframe and counter style identifiers.
+
+
+## Install
+
+With [npm](https://npmjs.org/package/postcss-merge-idents) do:
+
+```
+npm install postcss-merge-idents --save
+```
+
+
+## Example
+
+This module will merge identifiers such as `@keyframes` and `@counter-style`,
+if their properties are identical. Then, it will update those declarations that
+depend on the duplicated property.
+
+### Input
+
+```css
+@keyframes rotate {
+    from { transform: rotate(0) }
+    to { transform: rotate(360deg) }
+}
+
+@keyframes flip {
+    from { transform: rotate(0) }
+    to { transform: rotate(360deg) }
+}
+
+.rotate {
+    animation-name: rotate
+}
+
+.flip {
+    animation-name: flip
+}
+```
+
+### Output
+
+```css
+@keyframes flip {
+    from { transform: rotate(0) }
+    to { transform: rotate(360deg) }
+}
+
+.rotate {
+    animation-name: flip
+}
+
+.flip {
+    animation-name: flip
+}
+```
+
+
