Hi guys ? I tried to animate the ':: before' pseudo-element of a button in a React application with Styled-Components ... I know, it's a bit crazy ?   But, unfortunately, I did not have much success, here is my code ....   import React, { Component } from 'react'; import styled from 'styled-components'; import { TweenLite, CSSPlugin, CSSRulePlugin } from 'gsap/all'; const ButtonElement = styled.button` width: 200px; height: 60px; border-radius: 30px; line-height:
