Differences between background_color and theme_color in a PWA manifest
Let’s start with the background_color . This property plays a crucial role in the visual presentation of your PWAon various platforms.
Androidgenerates a splash screen for your app based on the background_color specified in the manifest. This creates a visually cohesive experience for users during the initial loading phase.
If you use Progressier, this color is also automatically used for the splash screens on iPhonesand iPads.
This background_color parameter also controls the color of the body of a desktop app during its loading phase.
Now, let’s explore the theme_color , which serves as the manifest equivalent of the theme-color HTML meta tag. Its primary role is to control the color of the status bar on your PWA.
theme_color is used while the app is loading. After the initial loading phase, browsers typically look to the theme-color in your code. If both exist, the meta tag property takes precedence.
In essence, the theme_color property in the manifest mainly influences the status bar’s color during the splash screen phase. For post-loading color adjustments, it’s more convenient to rely on the theme-color meta tag, which can be easily modified on the client side.
Note that the theme-color meta tag can also affect the URL bar’s appearance in light mode. In dark mode, most browsers automatically choose a dark shade for the URL bar and its surroundings.
To simplify your PWAdevelopment, consider using the same value for theme_color as you do for background_color . This approach ensures a seamless splash screen experience.
