title: I want to show opacity:1 for input[type="number"] placeholders
body: <p>I have one form having <code>input[type="number"]</code>.</p>
  
  <p>Placeholder shows reduced opacity on browsers.
  I want to show <code>opacity:1</code> for input placeholders.
  It is showing correct for <code>input[type="text"]</code> but not for  <code>input[type="number"]</code>.</p>
  
  <p>Not getting why is it so.</p>
  
  <p><strong>CSS</strong>:</p>
  
  <pre><code>input::-moz-placeholder{
    opacity: 1
  }
  
  textarea::-moz-placeholder{
    opacity: 1
  }
  </code></pre>
  
  <p>Can anyone help me?</p>
