kotlin-css

Platform-agnostic CSS primitives.

Getting Started

kotlin-css is a DSL for authoring stylesheets in Kotlin. The DSL supports most common CSS properties and values, including animations, transforms, shadows, flexbox, and grids. SVG properties are not supported yet, contributions are welcome.

kotlin-css is a low-level library. After constructing a stylesheet you can serialize it into a string and do with it as you please:

val styles = CssBuilder().apply {
body {
margin = Margin(0.px)
padding = Padding(0.px)

animation(
duration = 500.ms,
iterationCount = IterationCount.infinite,
fillMode = FillMode.backwards,
direction = AnimationDirection.alternate,
) {
to {
backgroundPosition = RelativePosition.left
}
}

backgroundImage = linearGradient(90.deg) {
colorStop(Color.black)
colorStop(Color.transparent)
}

transform {
translateY(0.px)
}
}
}

styles.toString()
