'Sign in & Slide Out format

I have a question and would love to get some feedback from you all. I'm stuck in a situation with my code that will not slide left to right. I have a SignUp/SignIn form and I need the slide in animation going left to right when you click either those 2 buttons. I feel like I have everything intact but it just does not want to work! :( Any help will be a blessing.

window.onload - function() {
  const signupButton = document.getElementById('signup');
  const signinButton = document.getElementById('signin');
  const container = document.getElementById('container');

  signUpButton.addEventListener('click', () => {
    container.classList.add("right-panel-active");
  });

  signInButton.addEventListener('click', () => {
    container.classList.remove("right-panel-active");
  });

}

You just have a few typo in your javascript code . Your "signup" and "signin" should be "signUp" and "signIn"

const signUpButton = document.getElementById('signUp');
const signInButton = document.getElementById('signIn');
const container = document.getElementById('container');

signUpButton.addEventListener('click', () => {
    container.classList.add("right-panel-active");
});

signInButton.addEventListener('click', () => {
    container.classList.remove("right-panel-active");
});

Here is the codepen if you want to see it in action => https://codepen.io/l0609890/pen/dyyKBeo

In React we don't directly mutate the DOM. It is also considered anti-pattern to query the DOM to access the DOMNodes (document.getElementById), use React refs instead to gain access to the underlying DOMNodes. I have converted it in react hope it helps

In this case you should use and update some React state to conditionally add the "right-panel-active" class to the ".container" div element.

const SignInForm = () => {
  const [swapPanel, setSwapPanel] = useState(false);

  const signUpButton = () => {
    setSwapPanel(true);
  };
  const signInButton = () => {
    setSwapPanel(false);
  };

  return (
    <div className="sigin">
      <div
        className={["container", swapPanel ? "right-panel-active" : null]
          .filter(Boolean)
          .join(" ")}
        id="container"
      >
        <div className="form-container sign-up-container">
          <form action="#">
            <h1>Create Account</h1>
            <div className="social-container"></div>
            <span>or use your email for registration</span>
            <input type="text" placeholder="Name" />
            <input type="email" placeholder="Email" />
            <input type="password" placeholder="Password" />
            <button onClick={signUpButton}>Sign Up</button>
          </form>
        </div>
        <div className="form-container sign-in-container">
          <form action="#">
            <h1>Sign in</h1>
            <div className="social-container"></div>
            <span>or use your account</span>
            <input type="email" placeholder="Email" />
            <input type="password" placeholder="Password" />
            Forgot your password?
            {/* <a href="#">Forgot your password?</a> */}
            <button onClick={signInButton}>Sign In</button>
          </form>
        </div>
        <div className="overlay-container">
          <div className="overlay">
            <div className="overlay-panel overlay-left">
