来自支点的CSS和ReaKit

Question

我用Fulcro编写了一个小的实验应用程序"2.6.0-RC8“。如果你运行它，你会看到小猫图片下面的文字--“卡片的描述”是红色的。这很好-一切都很顺利。但是，小猫图片下面的两个按钮应该是，而不是，而是与文本不同的按钮。“按下主”按钮的文本应为白色，其背景应为红色。我做错了什么？

(ns applets.reakit-test.core
  (:require [fulcro.client :as fc]
            [fulcro.incubator.ui.reakit :as rk]

            [fulcro-css.css-injection :as injection]
            [fulcro.client.dom :as dom]))

(def red "#FF0000")

(defsc PrimaryButton [_ {:keys [text]}]
  {:query         [:text]
   :initial-state (fn [p] {:text p})
   :css           [[:.primary
                    {:background-color red

组件Experiment中的查询是错误的。它应该是一个连接：[{:but-primary (prim/get-query PrimaryButton)}]
