In Vue 2,  the template tag can only take one root element. Even if we had just two <p> tags, we had to enclose them within a <div> tag to get it working. Because of this, we had to change the CSS code as well in the parent component so that it looked as expected.

In Vue 3, this restriction is lifted. There is no need for a root element anymore.

We can use any number of tags directly inside the <template></template> section:

<template>
  <p> Count: {{ count }} </p>
  <button @click="increment"> Increment </button>
  <button @click="decrement"> Decrement</button>
</template>

Equivalent code in Vue 2:

<template>
  <div class="counter">
    <p> Count: {{ count }} </p>
    <button @click="increment"> Increment </button>
    <button @click="decrement"> Decrement</button>
  </div>
</template>
