Ktor CSS DSL

We have the HTML page:

get("/html") {
    call.respondHtml(HttpStatusCode.OK) {
        head {
            link(rel = "stylesheet", href = "/style.css")
        }
        body {
            h1("greeting") {
                +"Hello user!"
            }
        }
    }
}

Styles:

get("/style.css") {
    call.respondCss {
        rule(".greeting") {
            color = Color("#FF0000")
            color = Color("#00FF00")
            color = Color("#0000FF")
        }
    }
}
