import React, { useState } from "react";
import "./App.css";

export default function App() {
  const [profileImage, setProfileImage] = useState(
    "https://cdn.pixabay.com/photo/2015/10/05/22/37/blank-profile-picture-973460_960_720.png"
  );

  const imageHandler = (e) => {
    const reader = new FileReader();
    reader.onload = () => {
      if (reader.readyState === 2) {
        setProfileImage(reader.result);
      }
    };
    reader.readAsDataURL(e.target.files[0]);
  };

  return (
    <>
      <div className="page">
        <div className="container">
          <h1 className="heading">Add your Image</h1>
          <div className="img-holder">
            <img src={profileImage} alt="" id="img" className="img" />
          </div>
          <input
            type="file"
            accept="image/*"
            name="image-upload"
            id="input"
            onChange={imageHandler}
          />
          <div className="label">
            <label className="image-upload" htmlFor="input">
              <i className="material-icons">add_photo_alternate</i>
              Choose your Photo
            </label>
          </div>
