Why XamlCSS For XAML?

Concise

Styling with (s)css gives a more concise declaration of your styles. XamlCSS even supports a subset of SCSS features like selector nesting, css-variables and mixins. This enables you to make your declarations even more concise.

Freely Combine Styles

Other than vanilla Xaml-styles, css allows you to freely combine styles - no BasedOn restriction. Even better, this is done for you behind the curtains!
And if you really want to combine styles yourself use @extend.

Semantic Meaning

Semantic meaning can be conveyed, i.e. is your ui-element important, a warning, a header or a sub-header? This is achieved by using css-classes.

Based On View-Hierarchy

Css takes into account where inside your view-hierarchy your element gets added. No need to manually assigning a style.
It also detects that an element was added or removed.
In combination with semantic selectors you can style a button differently just because it is in a warning dialog. And if you want to create a dark, a light and a custom theme, just switch the css-class-name on your root view-element and all elements update themselves automatically.

Support For Xaml-Features

You can use markup-extensions and triggers in your (s)css.

In css you cannot declare an instance of an object as you can do in xaml. A Storyboard for example must be declared as usual in a ResourceDictionary but then can be referenced in css with a markup-extension.

Designer Support

XamlCSS builds on top of the native Xaml-Style implementations, so it works with the WPF and UWP designer. For Xamarin.Forms there is LiveXAML.
