How to change v-dialog css styling dynamically-CodePudding

The goal is to be able to resize a v-dialog on click of a button. Usually I can apply dynamic css classes to vuetify components via :class prop. However, v-dialog requires use of the content-class in order to apply css class to it.

How can I accomplish something like code below on a v-dialog:

  <v-dialog
    persistent
    scrollable
    v-model="dialog"
    :class="{ 'my-css-class-name': myBooleanFlag }"
    style="position: relative;"
  >

CodePudding user response：

Try with :content-class="myBooleanFlag ? 'my-css-class-name' : ''" :

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  data() {
    return {
      myBooleanFlag: true,
      dialog: true
    }
  }
})

.my-css-class-name {
  background: violet;
  height: 100px;
}
