Dialog and overlay size with vuetify 3

This is my dialog code:

<template>
  <div class="text-center">
    <v-dialog v-model="dialog" width="500">
      <template v-slot:activator="{ on, attrs }">
        <v-btn
          color="red lighten-2"
          dark
          v-bind="attrs"
          @click.stop="dialog = true">
          Click Me
        </v-btn>
      </template>

      <v-card>
        <v-card-title class="text-h5 grey lighten-2">
          Privacy Policy
        </v-card-title>

        <v-card-text>

        </v-card-text>

        <v-divider></v-divider>

        <v-card-actions>
          <v-spacer></v-spacer>
          <v-btn
            color="primary"
            text
            @click="dialog = false"
          >
            I accept
          </v-btn>
        </v-card-actions>
      </v-card>
    </v-dialog>
  </div>
</template>

<script>
  export default {
    data () {
      return {
        dialog: false,
      }
    },
  }
</script>

As you see the width of the dialog is 500 <v-dialog width="500">. And this is the result I get:

As you see grey overlay width is also 500px. Is this correct? I expected that grey overlay width will be 100%, but dialog with with=500px will be in the center of the screen. Is it possible to set their sizes with <v-dialog> attributes or I should modify css rules?

Answer

There are some difference in dialog layout between Vuetify 3 and Vuetify 2. The below images is taken from example in their docs.

Vuetify 2:

Vuetify 3:

As you can see, in Vuetify 2 the overlay is an independent element and width: 500px added to the dialog while in Vuetify 3, the overlay contains dialog content and width: 500px added to the overlay. That causes the result you get. I’m not sure it’s expected behavior or not because Vuetify 3 is still in alpha version but for now, you can get your expected result by moving width="500" from v-dialog to v-card in your code.
