This one liner jQuery snippet will force your browser to go to the top of your page:
1.
$(
'html, body'
).animate( { scrollTop: 0 }, 0 );
If you want to add some smooth scrolling:
1.
$(
'html, body'
).animate( { scrollTop: 0 },
'slow'
$("h3").click(function(){
$(‘html, body’).animate({ scrollTop: 0 }, ‘slow’);
})
