How to use css to remove a blue highlight from button
<p>Please check the screenshot below. I basically want to remove the blue highlight that's added to my button when active click is activated. I would like to remove this effect as well from my input text box. To keep it from showing up when I'm clicked on it.</p>

<p>Thanks in advance.  </p>
