What about some jQuery with IronRouter?
Router.configure({
load: function() {
$('.content').animate({
left: "-1000px",
scrollTop: 0
}, 400, function() {
$(this).animate({ left: "0px" }, 400);
});
});
What I also do to make a smooth transition between pages is to use a simple fadeIn/fadeOut.
Router.configure({
load: function() {
$('html, body').animate({
scrollTop: 0
}, 400);
$('.content').hide().fadeIn(800);
}
});
