title: How do I style the borders of a formik error field?
body: <p>I know how to style it with regular form inputs/selects/etc, but I have switched from using those to Formik Field, and the above doesn't work the same way.</p>
  
  <pre class="lang-js prettyprint-override"><code>&lt;Formik
    initialValues={{
      example: ''
    }}
    validate={(values) =&gt; {
      const errors = {};
  
      if (!values.example) errors.example = 'Required';
  
      return errors;
  
    }}
    onSubmit={this.handleSubmit}
    render={formProps =&gt; {
      return (
        &lt;Form&gt;
          &lt;Field type='text' name='example' /&gt;
          &lt;ErrorMessage name='example' /&gt;
        &lt;/Form&gt;
      )
    }} /&gt;
  </code></pre>
  
  <p>So how would I change the border of the input from whatever it is normally to red if it is empty on submit?</p>
