Both Blazor and .NET MAUI are great and Powerful frameworks. Using .NET MAUI, you can build fully native cross-platform apps and build web apps completely in C# with Blazor.
But when you combine them with the MAUI Blazor template, you need to know that it should feel like a mobile app, not a web page! So, in this article, I will show you some tips and tricks.
Disable selecting content and texts
There is no need to select all texts and contents in your app! So, you can disable it in your CSS with these properties:
user-select: none;
-webkit-user-select: none;
Remove the default tapping effect
Mostly in mobile devices, when you tap on clickable elements like a tag, it shows some effects. In my experience, Android was showing an ugly blue color and in iOS was a gray one. So, give it your own beautiful effect using active selector in CSS and remove the default one with this CSS property:
-webkit-tap-highlight-color: transparent;
Annoying scroll animation
Sometimes you don’t want your app (mostly iOS) to have animation when the scroll hits the end of it, so you can disable it with this CSS property:
overscroll-behavior: none;
Handling Safe areas
Don’t worry it’s not Blazor or MAUI’s fault that your content is in the Status bar or Home bar. You can fix it in CSS like this:
@supports (-webkit-touch-callout: none) {
body {
padding-top: env(safe-area-inset-top);
padding-right: env(safe-area-inset-right);
padding-bottom: env(safe-area-inset-bottom);
padding-left: env(safe-area-inset-left);
}
}
Changing Android default colors
For those who are not familiar with native stuff, you can change the accent color and status bar color of your Android app from YOURPROJECTNAME\Platforms\Android\Resources\values\colors.xml.
Annoying startup background
When you run your app, you see a “Loading…” text with a white background so let’s fix that!
For “Loading…” text you need to remove it from a div tag with app id in your index.html, then access the BlazorWebView’s handler in your MainPage.xaml.cs and change the default background color of the platforms that you need like this:
BlazorWebViewHandler.BlazorWebViewMapper.AppendToMapping("CustomBlazorWebViewMapper", (handler, view) =>
{
#if WINDOWS
//Workaround for WinUI splash screen
if (AppInfo.Current.RequestedTheme == AppTheme.Dark)
{
handler.PlatformView.DefaultBackgroundColor = Microsoft.UI.Colors.Black;
}
#endif
#if IOS || MACCATALYST
handler.PlatformView.BackgroundColor = UIKit.UIColor.Clear;
handler.PlatformView.Opaque = false;
#endif
#if ANDROID
handler.PlatformView.SetBackgroundColor(Android.Graphics.Color.Transparent);
#endif
});
By the way, I already made a sample repo containing all of the code we discussed. You can have it from this link:

Happy coding ;D
