title: center Label in v-text-field
body: <p>hello I have tried different solutions to center the label in my v-text-field unfortunately none of them worked.
  please find the code below : </p>
  
  <p>html code</p>
  
  <p><code>&lt;v-text-field dark class="centered-input" label="your code"&gt;&lt;/v-text-field&gt;</code></p>
  
  <p>css code </p>
  
  <pre><code>    .centered-input &gt;&gt;&gt;  label {
          color: white;
          font-size:20px;
          text-align: center;
      }
  </code></pre>
  
  <p>Is there a way to align my label with vuetify</p>
