Question

我是Vue的新手。我已经开始使用类样式的绑定语法。我在CSS中定义的header和footer类没有显示，尽管在component标签中引用了它们。我似乎不知道为什么。

我尝试过将类放入组件中，但它们似乎也未显示在组件中。我感觉我必须以某种方式在Vue App初始化程序中绑定类？

谢谢！

您可能只需要向CSS添加边框样式属性。您在此处添加的内容将不显示边框：

.footer {
  border: 2px green;
}
.header {
  border: 2px blue;
}

但这会：

.footer {
  border: 2px solid green;
}
.header {
  border: 2px solid blue;
}

Vue-组件CSS类未使用类样式绑定显示在应用中
