Implementing CSS animations in ReactJS: A guide to activating onClick and onHover events

Is there a way to activate the onClick and onHover CSS animations for the ReactJS button component below?

I attempted to use ref = {input => (this.inputElement = input)}, but I only see the animation when clicking the button.

          <td>
            {this.state.buttons.slice(0, 4).map(btn => (
              <button
                onClick={() => this.handleClick(btn)}
                key={btn}
                className={this.getBadgeClasses(btn)}
              >
                {btn}
              </button>
            ))}
          </td>

It is important that I am able to trigger both animations using a keyboard event.

Answer №1

Essentially, the action onClick is triggered when the button is clicked using either the mouse or keyboard (by pressing Enter or Space key).

When you hover over the button, the browser activates onMouseOver, and if you focus on the button using a keyboard, the browser triggers onFocus.

It's a common practice to combine styling for both :hover and :focus. To incorporate CSS animation to buttons, simply include :focus in the style like this:

.btn-classes:hover,
.btn-classes:focus {

}

However, if you want to implement JavaScript animation to the component, add the onFocus prop to the button. The following code snippet may be useful:

<td>
  {this.state.buttons.slice(0, 4).map(btn => (
    <button
      onClick={() => this.handleClick(btn)}
      onFocus={() => this.handleFocus(btn)}
      key={btn}
      className={this.getBadgeClasses(btn)}
    >
      {btn}
    </button>
  ))}
</td>
