Animation in React

Start with CSS: toggle a class, transition opacity/transform. That’s enough for toasts and accordions. Framer Motion / react-spring when you need layout animation or exit transitions. Don’t open with a 40kb animation library in a fresher viva.

Animation in React — show true → toast in (CSS transition). Don’t start with a heavy animation library in viva.

Exam tip

CSS first. Library when layout moves.

Example

// Animation
export default function Toast({ show }) {
  return <p className={show ? "toast in" : "toast"}>{show ? "Saved" : ""}</p>;
}

Animation in React — show true → toast in (CSS transition). Don’t start with a heavy animation library in viva.

Short notes

First : CSS class + transition.
Later : Motion / spring.
Traplibrary for a fade-in.
