title: how to remove ngb-pagination active focus/blur
body: <p>I'm having trouble figuring out how to remove the focus/blur of the active clicked number. When I click outside of paginator it goes away, but I don't want it to appear at all when I click a button. I can't  find the correct CSS style to get rid of the border blur/focus.
  I'm using ngb-pagination.  I appreciate any help!</p>
