<h1>Example with 'v-if', 'v-else-if' and 'v-else'</h1>

<p>In this example all three directives 'v-if', 'v-else-if' and 'v-else' are used together.</p>

<p>The v-else part of the if-statement is active because the sentence does not contain 'pizza' or 'burrito'.</p>

<div v-if="text.includes('pizza')">
    <p>The text includes the word 'pizza'</p>
    <img src="img_pizza.svg">
  </div>

<div v-else-if="text.includes('burrito')">
    <p>The text includes the word 'burrito', but not 'pizza'.</p>
    <img src="img_burrito.svg">
  </div>
  
  <p v-else>The words 'pizza' or 'burrito' are not found in the text</p>

</div>
