Question: CSS to Xamarin.Forms

[juucustodio]

The Xamarin.Forms 3.0 and latest versions have support to CSS.
How the situation about this ? MAUI will support this feature ?

I think it's best to remove this. It is additional code to maintain, additional docs to maintain, confusion for users, and extra work needed to add or change controls in the repository.

For interested users this function could be in a separate community-maintained repository, usable via a separate nuget package. CSharp source generators would allow this to happen without any need to provide support in the main repo.

It's important to keep the main repo as small and clean as possible for maintainability.

I much prefer XAML styling, but there are currently things you can do with CSS you can't do with XAML styling.

Whether CSS is dropped or not, I would like XAML styling to support advanced selectors.

Genuinely curious about how many people use CSS styles over XAML styles? I know this is purely anecdotal, but I’ve never seen it used outside of examples.

I’d agree with @charlesroddie, add support via NuGet for people who want it.

I agree with @charlesroddie opinion. Maybe is a solution of this case.

Responding about your question... I know people that use CSS to Xamarin.Forms. But the idea not is choice between XAML Styles and CSS. The people in this case use together.

Just putting in a vote to keep CSS styling in the core. We use it exclusively for styling in our framework and love the flexibility and easy it provides.

maybe using the generic host structure (issue spec) we can split these "styles features" to optional modules (nuget).
So, the developer can configure one, or both, on startup.cs

something like...

Host.CreateDefaultBuilder()
    .ConfigureStyles(settings => settings.UseXamlStyles().UseCssStyles())

Where UseXamlStyles and UseCssStyles are extension methods from nuget packages

To me, is the linker that should be in charge to strip away the css assemblies if not used in app :)
I think that this is how it works today.

I'm pretty sure css will not be removed from MAUI, in some cases you can do some things not possible with xaml styling.

This is a good point!
In my opinion, Linker is an advanced tool that some developers don't use properly...
Splitting some components can be a way to reduce app sizes for these "novice developers".
Btw, for me, it makes no sense to include code to remove it later.
Off course, my suggestion will increase assemblies to load, this will be a problem

But I don't know, maybe I'm just talking about something that has already been discussed 🤷‍♂️

I think that makes sense to maintain the CSS support if we have web support, as described here #62. Also, if the Mobile Blazor Bindings becomes a thing, the style using CSS will be more useful than XAML style (in this case).

[MihirJayavant]

CSS support is important for Mobile Blazor Bindings. It would be bad idea to use XAMLstyles there
