How to Implement Inline CSS Pseudo-Elements (like ::after) in React?

Inline CSS Pseudo Elements in React

When developing React components, one may encounter the need to add CSS pseudo classes inline. However, React does not natively support applying properties directly to pseudo elements like ::after.

To overcome this challenge, React utilizes its component-based architecture. Instead of creating a new element using CSS's ::after, a new element should be created via React. A custom React component can encapsulate this behavior.

To apply additional properties to the pseudo element, such as position and -webkit-filter, a style object is used. For special attributes like -webkit-filter, the dashes are removed, and the next letter is capitalized (e.g., WebkitFilter).

For example, to create a React component that adds an ::after element with the desired properties:

class PseudoElement extends React.Component {
  render() {
    return (
      <div>
        {this.props.children}
        <div>

This component can then be used within the parent component as follows:

render() {
  return (
    <PseudoElement>
      <span>Something</span>
    </PseudoElement>
  );
}

This approach allows for the addition of inline CSS pseudo elements in React, providing greater flexibility and control over component styling.
