Why is my Styled-Components (React dependacy) not working?

Time:12-22

Actually, I have two questions

  1. The First one is that Why is the following code using styled-components not working, I removed node modules, installed it again globally etc and it's not working. The output render is blank.
  2. Am I using the Pseudo classes correctly in styled components If not please show me
  3. I would really appreciate it if you could show me through the code I have.
  4. I will List my Js file plus the desired CSS below, I only want the CSS through styled-components
    import React, { useRef} from "react";
            import ReactDOM from 'react-dom/client';
            import Home from "../Dashboard/Home";

            import Bye from "./Login"
            import styled from "styled-components"
            function Register(){
               const name=useRef()
               const email=useRef()
               const password=useRef()
               const root = ReactDOM.createRoot(document.getElementById('root'));
               const handleClick=()=>{
                   if(name.current.value&&email.current.value&&password.current.value)
                  {
                    localStorage.setItem("name",name.current.value)
                    localStorage.setItem("email",email.current.value)

It is important to define your styled components outside of the main react component, otherwise it will be recreated on every single render pass. Defining a styled component within the react component will prevent caching and drastically slow down rendering speed, and should be avoided.

import React, { useRef } from 'react';
import ReactDOM from 'react-dom/client';
import styled from 'styled-components';

const Body = styled.div`

Here is my solution. Keep styled component outside of Register component.

import ReactDOM from 'react-dom/client';
import Home from '../Dashboard/Home';

import styled from 'styled-components';

  margin: 0;
  padding: 0;
  font-family: 'Poppins', sans-serif;
  display: flex;
  justify-content: center;
  align-items: center;
  min-height: 100vh;
  background: black;
`;
const Box = styled.div`
  position: relative;

  width: 600px;
  height: 540px;
  background: #1c1c1c;
  border-radius: 8px;
  overflow: hidden;

  &:before {
    content: '';
    position: absolute;
    top: -50px;
    left: -50px;
    width: 600px;
    height: 440px;
    transform-origin: bottom right;
    background: linear-gradient(
      0deg,
      transparent,
      transparent,
      #45f3ff,
      #45f3ff
    );

const Title = styled.h2`
