Overriding the CSS prefers-color-scheme Setting: A Comprehensive Solution

The advent of dark modes in major operating systems has necessitated the implementation of customizable themes for websites. However, the native @media (prefers-color-scheme: dark) CSS rule may not always align with user preferences or browser support.

Introducing CSS Variables and Themes

To overcome this limitation, we can leverage CSS variables and themes:

• Define default variables in the root element.
• Create a separate theme (e.g., "dark") with modified variables.
• In CSS styles, reference the variables instead of hard-coding the colors.

This approach provides a consistent way to apply themes dynamically.

JavaScript for Detection and Toggling

To detect the user's preferred or overridden theme, as well as to allow users to toggle between themes:

• Use JavaScript to check for the data-theme attribute, local storage, or @media query to determine the current theme.
• Implement a function to switch themes and set a local storage variable to persist the user's preference across page reloads.
• Add an event listener to a checkbox element to enable user toggling.

HTML for Toggling

Include a simple checkbox in your HTML to allow users to switch themes on demand.

Benefits of This Solution

This comprehensive approach offers several advantages:

• Automatic theme detection based on OS settings.
• User-controlled override of system themes.
• Consistency across browsers through CSS variables.
• Persistence of user preferences between page loads.
