IE, CSS: How to remove a highlight which appears, when click the button

Question

Take a look at this page in IE (I have the newest version, but it also happens in older versions.)

In above link there are two round buttons at bottom of the page. When you click the button, a semi-transparent highlight around the button appears. It doesn't appear in Mozilla or Chrome. Is it possible to remove it somehow?

Answer 1

Add an extra style in anchor tag.

style="background-color:transparent" 

Answer 2

TRY It. The below code of css is useful for remove the border and focus around the link or button.

a:focus{
 outline:none !important;
 }
