为什么我写在app.vue的样式不全局，就是对其他的组件没有影响

这里的class=“button”不能从app.vue那里获取样式，这是为什么？

应该是在app.vue那里的。main.js那里router的el是在#app的，那layout.vue那里应该是映射，但是就是传递不到css。

理论上不是，只要不加scoped，都会被放到全局样式里，会给所有子组件共享，但子组件的全局样式影响不到父组件。你的问题，我不清楚layout是怎么挂载到app.vue上的，这个过程可能有问题，我的全局样式就是直接写到app.vue里的，再暴力点的做法是build之后看一下打包的全局css，检查一下代码，看过程有没有报错。
