How does the snippet determine the theme to apply?

It first checks for a user's theme preference in localStorage. If it's 'system' or not set, it uses the 'prefers-color-scheme' media query to determine the system's theme setting and applies the appropriate theme.

If the user's theme preference in localStorage is explicitly set to 'light' or 'dark', the script directly applies the respective theme to the document.

The 'prefers-color-scheme' media query is used to check the system's theme setting when the user's preference is 'system' or not specified.

Is there error handling in this script?

Yes, the script includes error handling to manage any issues that may arise during its execution.

What does the script do in case of an error?

The script includes mechanisms to handle errors gracefully, ensuring that the website remains functional even if theme application encounters an issue.

Can this script be used for both light and dark themes?

Yes, the script is designed to apply either a light or dark theme based on user preference or system settings.

Where does the script store the theme preference?

The theme preference is stored in the browser's localStorage.

Does the script work across different browsers?

As long as the browser supports localStorage and the 'prefers-color-scheme' media query, the script should function properly.
