title: Html5 input type number not prevent plus, minus symbols
body: <p>I am using input type number and It's preventing character but it's unable to prevent plus, minus symbol or character. But I require to prevent all symbol.</p>
  
  <pre><code>&lt;input type="number"&gt;
  </code></pre>
  
  <p>I have worked on it and create my customise regex and it's working fine but I want to know why it's working like that for input type number and how we can fix that.</p>
