Anchors are handy for jumping around a page, but to add to the effect, use jquery's animate, which lets you scroll around an action and slowly scroll to where you want to jump to.

Scroll to the top:

$('.scroll_top').click(function(){$('html,body').animate({scrollTop: '0px'}, 800);});

Scroll to the specified location:

$('.scroll_a').click(function(){$('html,body').animate({scrollTop:$('.a').offset().top}, 800);});
