const container = document.getElementById('container');

Explanation
- HTML Structure:
- The HTML includes two forms, one for sign-up and one for sign-in, each within its own container.
- There is also an overlay container that switches between sign-in and sign-up prompts.
- CSS Styling:
- Basic reset and styling for the body and container.
- The forms and overlay panels are styled and positioned using absolute positioning.
- Transitions are used to animate the switching between sign-in and sign-up forms.
- JavaScript Functionality:
- The JavaScript listens for clicks on the “Sign Up” and “Sign In” buttons to add or remove the
right-panel-activeclass on the container, which triggers the CSS transitions to switch forms.
- The JavaScript listens for clicks on the “Sign Up” and “Sign In” buttons to add or remove the
This setup provides a smooth transition between Sign-In and Sign-Up forms, making for a user-friendly experience.
