title: How to change *just* the padding of a button in html on iOS
body: <p>I have an html page with a button and I want to get rid of its padding.  The obvious</p>
  
  <pre><code>padding: 0px !important;
  </code></pre>
  
  <p>didn't work.  Writing</p>
  
  <pre><code>-webkit-appearance: none;
  padding: 0px;
  </code></pre>
  
  <p>did, but it got rid of all the other iOS-like formatting.</p>
  
  <p>Everything works fine on desktop.  This happens on iOS.  I haven't tested Android.</p>
  
  <p>Is there any way to change just the padding without everything else?  Is there any way to save a copy of the style so that I can restore it?  I'm happy with javascript-based solutions (including d3, for any difference that makes).</p>
