Code has no issues, is very neat and well-done, and JavaScript is well-executed and neatly arranged. Html code is neatly arranged, making reading the code easy and efficient.
The styles in your styles.css are also very well arranged and have no issues however, to make it more readable and accessible you can try to comment on which portion of the styles is used in which section. For easier accessibility.
