| Description | 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. | UltraBrainstomer's Template Customizer is a versatile tool designed for users to tailor and preview website themes in real time. The customizer offers multiple themes, including Default, Semi-Dark, and Bordered, and provides light and dark modes. Users can adjust layout settings like Static, Fixed, or Dropdown on hover menus, as well as opt for a fixed navbar or footer. Additionally, there are RTL direction options for different languages, enhancing the overall flexibility and personalization capabilities of the tool. |
