title: How can I change or remove HTML5 form validation default error messages?
body: <p>For example I have a <code>textfield</code>. The field is mandatory, only numbers are required and length of value must be 10. When I try to submit form with value which length is 5, the default error message appears: <code>Please match the requested format</code>    </p>
  
  <pre><code>&lt;input type="text" required="" pattern="[0-9]{10}" value=""&gt;
  </code></pre>
