Validate the diagnostic

Confirm the reported code matches this rule before you edit it.

Confirm the reported code matches react-doctor/no-mixed-animation-owners. Compare it with the Before example and verify the same API, framework, and execution context. Treat it as a false positive only when one of those conditions differs.

Compare the code

The corrected pattern shows a focused way to address the diagnostic.

Reported pattern

import { motion } from "motion/react";
const Demo = () => (
  <>
    <motion.div
      animate={{ x: 10 }}
      className="!transition-none"
      style={{ transition: "transform 200ms" }}
    />
    <motion.div
      animate={{ opacity: 1 }}
      className="!duration-0 transition-opacity"
      style={{ transitionDuration: "200ms" }}
    />
    <motion.div
      animate={{ x: 10 }}
      className="transition-transform"
      style={{ transitionProperty: "opacity" }}
    />
    <motion.div
      animate={{ opacity: 1 }}
      className="transition-opacity duration-0"
      style={{ transitionDuration: "200ms" }}
    />
  </>
);

Corrected pattern

import { motion } from "motion/react";
const Demo = () => (
  <>
    <motion.div animate={{ x: 10 }} className="!transition-none" />
    <motion.div animate={{ opacity: 1 }} />
    <motion.div
      animate={{ x: 10 }}
      style={{ transitionProperty: "opacity" }}
    />
    <motion.div animate={{ opacity: 1 }} />
  </>
);

How to fix

Use the corrected pattern as a reference. Preserve behavior that the rule does not require you to change.

Copyable fix prompt

Copy this self-contained prompt into your coding agent after you confirm the diagnostic.

Fix every confirmed react-doctor/no-mixed-animation-owners diagnostic in the current repository. Required change: - Give each property one animation owner. Remove its CSS transition when Motion controls it, or move the CSS transition to a different element or property.

Reference transformation:Before:

import { motion } from "motion/react";
const Demo = () => (
  <>
    <motion.div
      animate={{ x: 10 }}
      className="!transition-none"
      style={{ transition: "transform 200ms" }}
    />
    <motion.div
      animate={{ opacity: 1 }}
      className="!duration-0 transition-opacity"
      style={{ transitionDuration: "200ms" }}
    />
    <motion.div
      animate={{ x: 10 }}
      className="transition-transform"
      style={{ transitionProperty: "opacity" }}
    />
    <motion.div
      animate={{ opacity: 1 }}
      className="transition-opacity duration-0"
      style={{ transitionDuration: "200ms" }}
    />
  </>
);

After:

import { motion } from "motion/react";
const Demo = () => (
  <>
    <motion.div animate={{ x: 10 }} className="!transition-none" />
    <motion.div animate={{ opacity: 1 }} />
    <motion.div
      animate={{ x: 10 }}
      style={{ transitionProperty: "opacity" }}
    />
    <motion.div animate={{ opacity: 1 }} />
  </>
);

Constraints: - Confirm the reported code matches the Before pattern. - Make the smallest change that fixes the root cause. - Preserve behavior and interfaces unrelated to this diagnostic. - Reuse existing project components, utilities, and conventions. - Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations. - Use existing brand assets, product facts, content, and design tokens. - Do not invent claims, customer data, typefaces, or artwork. - Adapt identifiers and framework details instead of copying blindly. - Do not disable the rule or suppress matching code. Verification: - Run focused tests for the changed behavior. - Run React Doctor and confirm this diagnostic no longer appears. - Report the files changed and any checks you could not run.
