title: Disable image button border
body: <p>I'm using asp.net ImageButton and it looks like:</p>
  
  <p><img src="https://i.stack.imgur.com/TWFT9.png" alt="enter image description here"></p>

  <pre><code>border: 0px;
  border-style:none;
  </code></pre>
  
  <p>But same result.. How can I solve that? </p>
