Styles support

For now it has only direct support for styles

Style.display(.flex)
Style.position(.absolute)
// etc.

Almost all keys for styles are already here, but factories for values are still in development, anyway you can use strings for initialization for now

Style.margin("10pt")

Transform functions are implemented btw :)

Style.transform(.translate(x: 10%))

// Or you can create custom ones like so

extension Style.TransformFunction {
    func someNew3DFunction(
        x: Dimension.Length, 
        y: Dimension.Length, 
        z: Dimension.Length
    ) -> Self {
        Style.TransformFunction(
            name: "someNew3DFunction",
            arguments: [
              	x.erased,
                y.erased,
                z.erased
            ]
        )
    }
}

Use StylesCollections for elements

let styles: StylesCollection = [ // the same as `let styles: [Style] = [...`
    .alignSelf(.center),
    .background(Color.brown.hex(uppercase: true, hashTagPrefix: true)),
    .borderRadius(1.in.px.render())
]
styles.render() // "align-self:center;background:#A52A2AFF;border-radius:1.0px;"

Dimensions

Dimensions are present but not integrated in styles factory, so u can render them manually for now

Style.margin(10.in.pt.render())
// the same as
Style.margin(Dimension.Length(value: 10, unit: .pt).render())
// or
Style.margin(Dimension.Length.pt(10)).render())
//  Need for `render()` call will be removed in beta releases (It's currently alpha)

Also you can convert some dimensions or replace units

// - Convert
1000.in.ms // 1000 ms
1.in.s.converted(to: .ms) // 1000 ms

1.in.kHz // 1kHz
1000.in.hz.converted(to: .kHz) // 1kHz

// - Replace units
1.in.s.in(.ms) // 1ms
1.in.s.value.in.pt // 1pt

// - Other
10% // Dimension.Length(value: 10, unit: .percent) or 10.in.percent

Corneres & Edges are supported too

Colors

See GenericColor and Palette for more.

Style.background(color: .livingCoral)
Style.foreground(color: .hex("ffffff")!)

Fonts

I'm gonna provide a static factory for google fonts later, and Font type behaviour may change.

Style.fontFamily("arial")
Style.fontSize(.pt(10))
Style.fontWeight(.bold)

Installation

.package(
    url: "https://github.com/MakeupStudio/CSSKit.git", 
    .upToNextMajor(from: "1.0.0-alpha.1.0")
)

Integration

You can use generateIntegration methods from CSSKit itself by passing needed arguments or use this tool for autogenerating integration code.

So it will generate all the needed fields for your container type, for example for HTML type it will look like

// MARK: - Implementation

extension HTML {

    internal func appendingStyle(_ style: Style) -> Self {
        <#Implementation#>
    }

}

// MARK: - Generated

extension HTML {
    
    public func alignContent(_ value: String) -> Self {
        appendingStyle(.alignContent(value))
    }

    public func alignItems(_ value: String) -> Self {
        appendingStyle(.alignItems(value))
    }
  
  	// ...
  
}

And you'll be able to use chaining like this

someHTMLInstance
    .display(.flex)
    .transform(.rotate(x: .deg(30)))

Hopefully I'll add more typo-free static factories & extend fonts support a bit next week

Feel free to open issues if you need any functionality
