How to remove focus from button after closing the "altertify" confirm modal?

I have a button with :hover and :focus css property. While hovering on it the color changes to red. Now when i click on it a Alertify confirm box appears and then i press ok or cancel the color changes to red again because of :focus property. How can i unbind :focus when clicked on ok or cancel.

 alertify.confirm('Confirmation', 'You clicked', function () {
                //do nothing
            }
            , function () {
                //do nothing

});

Solution

you have to just add this code in js file $(".btn-test").blur(); like this:

$(".btn-test").click(function(){

        $(".btn-test").blur();        
   

 alertify.confirm('Confirmation', 'You clicked', function () {
                //do nothing
            }
            , function () {
                //do nothing
            });

});

.btn-test:hover,.btn-test:focus{
background-color:red;
}
