Add this javascript, and a css rule for .selected and you should get the desired result.

$(function(){
    $('input.blackButton').live('click', function(e){
        var t = $(e.target);
        if (!t.hasClass('selected'))
            $('input.selected').toggleClass('selected');
        t.toggleClass('selected');
    });
});

Created a jsfiddle.
