<div v-if="dialogFoundation">

>Solution :
The best performance would be to use javascript plain. You can add Eventlistener top the modal trigger Element. In my example i use a button. If it triggered then you can use classList and assign the body a class. In my example .dark.
Vue version

<template>
<div id="app">
<h1>{{message}}</h1>
<p></p>
<button @click="doSomething">Modal</button>
</div>
</template>
<script>
export default {
data() {
return {
message: 'Welcome to Vue!'
};
},
methods: {
doSomething() {
const b = document.querySelector('body');
b.classList.toggle('dark');
}
}
};
