vue.js - 无法让 v-img 在 v-flex 内居中

Question

我是 Vue 和 Vuetify 的新手，我正在尝试构建一个登录屏幕。我无法让 v-img 在 v-flex 中居中。我已经尝试了很多东西，但我真的卡住了。我指的是右侧 v-flex 中的 Vue Logo 。

我无法让代码片段完全如上图所示，但我认为这并不重要，因为 Vue Logo 也没有在代码片段中居中。如果有更好的方法来创建如图所示的设置，我真的很想知道。正如我所说，我对此很陌生，仍在学习。

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  data: () => ({
      showPassword:false
    }),
})

编辑:我已添加 mx-auto上课 v-img ，现在它按预期工作。

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  data: () => ({
      showPassword:false
    }),
})
