FAQs

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.
What happens if no theme preference is set by the user?
If no theme preference is set, the script checks the system's theme setting via the 'prefers-color-scheme' media query and applies the corresponding theme.
How does the script handle explicit theme preferences?
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.
What is the role of 'prefers-color-scheme' in this script?
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?

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.
