What is the best way to incorporate transition effects into images as they appear on the screen?

I'm currently working on my React app and trying to add effects to images when they appear on the page. I have tried using the code below, but it doesn't seem to work as expected. I directly applied styles to the div tag because I couldn't get trigger effects like hovering or clicking to work. Could it be that I am approaching this in the wrong way?

JSS styles

column: {
  ...
  "& div": {
    transition: "all 0.5s ease-in-out"
  }
}

JSX

renderColumn(column) {
  return column.map((item, i) => (
    <div key={i}>
      <img ... />
    </div>
  ));
}

React Transition Group addresses this particular issue and is maintained by the React community. To implement it, follow these steps:

import { CSSTransitionGroup } from 'react-transition-group'
.
.
.
<CSSTransitionGroup
    transitionName="example"
    transitionEnterTimeout={500}
    transitionLeaveTimeout={300}
>
    <img/>
</CSSTransitionGroup>

In your CSS file, define the following styles to specify classes for enter/exit events:

.example-enter {
  opacity: 0.01;
}

.example-enter.example-enter-active {
  opacity: 1;
  transition: opacity 500ms ease-in;
}

.example-leave {
  opacity: 1;
}

.example-leave.example-leave-active {
  opacity: 0.01;
  transition: opacity 300ms ease-in;
}
