| Description | The Theme Handling Script dynamically manages the theme settings of the document based on the user's preference stored in localStorage or the system's color scheme preference. It ensures a seamless user experience whether they prefer light or dark themes by efficiently adding the corresponding class to the document. If there is no specified preference, the script defaults to the system preference. | This JavaScript snippet manages the website's theme based on user preferences. It retrieves the user's theme preference from localStorage; if the preference is 'system' or not set, it checks the system's theme setting via the 'prefers-color-scheme' media query. Depending on the outcome, it applies either a dark or light theme to the document. For explicit 'light' or 'dark' preferences, it directly applies the corresponding theme. Error handling is also incorporated to ensure smooth operation. |
