Assuming that your href attribute is linking to a div with the tag id with the same name (as usual), you can use this code:
HTML
Link to div

JAVASCRIPT – (Jquery)
$(“.sliding-link”).click(function(e) {
e.preventDefault();
var aid = $(this).attr(“href”);
$(‘html,body’).animate({scrollTop: $(aid).offset().top},’slow’);
});
