title: HTML5 Validation with Opera and Safari
body: <p>I am having a problem with the HTML5 validation on Opera and Safari. </p>
  
  <p>In Opera, the message bubble it's not displaying any text, and in safari the validation does not occur when i press the submit button. In IE, Mozilla or Chrome the validation works just fine. Could anyone tell why is this happening?</p>
  
  <p>The inputs that i have in my forms have the html5 standard validation, with the required attribute, and that's it.</p>
  
  <p>I tried to search this topic around the web, but didn't manage to find it.</p>
  
  <p>Please help me.</p>
  
  <p>Thanks</p>
