Now, the content slide animation will come in later, as shown below: How about creating an altogether custom animation? Let’s make a bounce animation.

There are a few ways to create animations in React, but all of them fall into two broad categories: CSS animations, which change visual state by applying CSS rules; and, JavaScript animations, which use JavaScript to change the properties of the element. In either of those categories, you can either implement the animation from scratch, or you can use a library. On the CSS side, you can compose your animations with CSS rules, or you can use third-party libraries like Animate.css.

Use actual CSS/JS to make the effects. You can learn most of it if you search for CSS3 animations (Mozilla dev docs are a good option). You could also use a library like Animate.css

Animate.css: This CSS animation library offers different pre-built animations that can be easily applied to elements on a website. Different animations in the library, such as fades, slides, flips, and more, can be used to animate CSS Grid layouts.
