title: Red asterisk after ng-required input (without label)
body: <p>I'm looking for a CSS rule to apply a red asterisk after the inputs with the <code>ng-required</code> attribute.</p>
  
  <p>The thing is, there is no label on those inputs, the placeholder is used as a label.</p>
  
  <p>Those 2 inputs for instance :</p>
  
  <pre><code>&lt;div class="row"&gt;
      &lt;div class="col-xs-6"&gt;
          &lt;input type="text" name="CACLastName" ng-model="cac.lastName" placeholder="NOM" ng-required="true" ng-disabled="$parent.isDisabled" class="form-control"/&gt;
      &lt;/div&gt;
      &lt;div class="col-xs-6"&gt;
          &lt;input type="text" name="CACFirstName" ng-model="cac.firstName" placeholder="Prénom" ng-required="true" ng-disabled="$parent.isDisabled" class="form-control"/&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>So I tried to play with <code>:after</code> but without success. Also, the <code>:required</code> only apply to the <code>required</code> attribute, not <code>ng-required</code>.</p>
