For example, in Dark Mode with Increase Contrast and Reduce Transparency turned on (both separately and together), you may find places where dark text is less legible when it’s on a dark background. Test your content to make sure that it remains comfortably legible in both appearance modes. In addition to using one mode or the other, people can choose the Auto appearance setting, which switches between light and dark appearances as conditions change throughout the day, potentially while your app is running. Worse, they may think your app is broken because it doesn't respond to their systemwide appearance choice.Įnsure that your app looks good in both appearance modes.
An app-specific appearance mode option creates more work for people because they have to adjust more than one setting to get the appearance they want.
Best practicesĪvoid offering an app-specific appearance setting. In Dark Mode, the system uses a dark color palette for all screens, views, menus, and controls, and may also use greater perceptual contrast to make foreground content stand out against the darker backgrounds. In iOS, iPadOS, macOS, and tvOS, people often choose Dark Mode as their default interface style, and they generally expect all apps and games to respect their preference. light-theme class inside of that we can use to override the dark mode properties, should the user want to toggle between the two modes.Dark Mode is a systemwide appearance setting that uses a dark color palette to provide a comfortable viewing experience tailored for low-light environments. The idea is to define the custom properties for both themes like we did before, wrap dark styles up in the prefers-color-scheme media query, then define a.
Let’s use the CSS custom properties approach to demonstrate how to do this. That’s why providing a way to manually override dark mode, despite the system settings, is a good idea. But what if users want to override their system preference for a site? Just because a user prefers dark mode for their OS doesn’t always mean they prefer it on a website. We just looked at how to account for a user’s system-wide color scheme preferences. There may even be other possible methods than what we have discussed. Sometimes a combination of methods will be the most effective route. Moreover, there’s nothing saying we can only use one method. On the other hand, if your project needs to support legacy browsers, then another approach will need to do instead. If you are doing a large project, for example, you might go with CSS properties to help wrangle a large codebase. The “right” method comes down to the requirements of your project. But a server-side solution like this is useful in persisting the user’s theme choice across page reloads, as we will see later. This method has an obvious downside: the page needs to be refreshed for the toggle to take place.
I am using a GET request (URL params) for the purpose of this demonstration.Īnd, yes, we can swap stylesheets just like we did in the second method. Then, we let our code (PHP in this case) apply the appropriate body class when the page is reloaded. We can have the user send a GET or POST request. This is a great approach if you prefer working directly in the markup. If we’re already working with a server-side language, say PHP, then we can use it instead of JavaScript. Here’s a script for a button that will toggle that class, for example: // Select the buttonĬonst btn = document.querySelector('.btn-toggle') ītn.addEventListener('click', function(). The trick here is to swap out a class that can be a hook for changing a style anywhere on the page.
