Learn how Framer Motion’s layout prop animates width and height changes with the FLIP technique, plus a ready‑to‑run toggle box example and performance tips.
Learn how to diagnose and resolve layout jumps and stuttering in Framer Motion by identifying CSS conflicts, fixing layoutId mismatches, and reducing browser reflows.
Framer Motion's layout prop automates FLIP animations for position and size changes. This post explains how it works, shows a reorderable list example, and covers performance traps in React 18 concurrent mode.
When building a modal with Framer Motion, pick the right animation strategy—Variants for reusable states, direct props for quick one‑offs, or useAnimation for event‑driven sequences. This guide compares the options, explains trade‑offs, and shows a concrete implementation.
Learn how Framer Motion's layout prop and layoutId create smooth DOM reordering and shared element transitions using the FLIP technique.
When a component tree undergoes a schema change—such as adding, removing, or reordering elements that are animated with Framer Motion—there is a risk that exit animations may be interrupted or that the rollback leaves the UI in an inconsistent state. Using `animatePresence` allows components to animate out before unmounting, but ensuring that the rollback pr
When a component’s display style switches from none to block , developers often rely on Framer Motion’s layout prop to animate the element’s entry. However, the FLIP algorithm cannot capture a start state for an element that has no measurable layout while hidden, so the animation is suppressed. Current behavior falls back to animating explicitly defined prop
Framer Motion's animation primitives depend on browser APIs, so inside the Next.js App Router they must sit behind a client boundary marked with use client . A small React application can therefore adopt motion.* components piece by piece while unconverted routes keep their existing CSS transitions. The interoperability question is what happens at the seam.
Goal: Verify whether Framer Motion's AnimatePresence component triggers its exit animations when a Next.js App Router route is unmounted via navigation. Constraint: AnimatePresence only animates children that it directly removes by tracking their key props, while the App Router removes route segments through its internal router rather than a React state chan
