title: Is there a way to stop manual input in a type=number but still allow changes with the "up/down" buttons?
body: <p>I have an input:</p>
  
  <pre><code>&lt;input type="number" name="amount" min="4" max="6" step="2" value="4" id="amount" /&gt;
  </code></pre>
  
  <p>And I don't have a normal submit button to submit the info (uses javascript).</p>
  
  <p>type=number works fine, but users can still type in any number they want, I would like to stop users from being able to type in the input, but still allow for changes using the "up/down" arrows that appear with type=number. I have tried researching but cannot find anything. Is this even possible?</p>
