title: How to style Vue Formulate input errors?
body: <p>I write a website with Vue.js and to handle user interface, I want to use Vue Formulate. All in all it works, but I have trouble to style input errors. So, I tried to make a very simple example to change the background color from the error list, but it doesn't work.</p>
  <p>That is my easy component:</p>
  <pre><code>&lt;template&gt;
    &lt;div&gt;
      &lt;p&gt;Test for VueFormulate&lt;/p&gt;
      &lt;FormulateInput
        type=&quot;text&quot;
        validation=&quot;required&quot;
      /&gt;
    &lt;/div&gt;
  &lt;/template&gt;
  
  &lt;script&gt;
  export default {
    name: 'HelloWorld'
  }
  &lt;/script&gt;
  
  &lt;style scoped&gt;
    li.formulate-input-error {
      background-color:green;
    }
  &lt;/style&gt;
  </code></pre>
  <p>After the site is loaded and the error list element is there, I can change the background-color in the Google Chrome devtools. But not bevor.</p>
  <p>I hope somebody can explain what I have to do to make it work.</p>
