title: How to make button background transparent?
body: <p>I have created one button and applied image (.png with transparent background) on it.<br>
  <img src="https://i.stack.imgur.com/L0alk.png" alt="enter image description here"><br>
  My button background is set on transparent but as you can see the background color is still there.<br>
  How can I make this work as it should?</p>
