javascript - scrollTop animate is laggy in chrome but works fine in firefox (background-size: cover issue?) -


edit: issue seems background-size: cover; in css. searching remedy on google now...

this site: bitco.tk

when click link in top navigation menu should animate , scroll down elements.

it works fine in ff, ie, , safari, in chrome it's laggy/choppy. here code:

$(document).ready(function() {   $('.restloc').on('click', function(e) {     e.preventdefault();     $("html, body").stop().animate({ scrolltop: ($('#locinfo').offset().top) -60 }, 'slow');   });   $('.restmenu').on('click', function(e) {     e.preventdefault();     $("html, body").stop().animate({ scrolltop: ($('#mlist').offset().top) -60 }, 'slow');   });   $('.restname').on('click', function(e) {     e.preventdefault();     $("html, body").stop().animate({ scrolltop: 0 }, "fast");   });  });

i have tried without e.preventdefault , .stop() doesn't make difference.

how can fix it?

after lot of googling found issue css background property. quickest solution found jquery plugin 'backstretch'.
