jquery - Hide a div when page is still, show on scroll movement up -


i want sticky header on chrome (?) on android.

ie, scroll down page, there no sticky header, scroll up, (or after 1 second) sticky header appears again.

then, when scroll down hides once more.

i think far better sticky header solution can find tutorials refer waypoints, , want based on movement, not fixed positions.

can give me bare bones example of this?

would great, thanks.

check working fiddle .i hope need..

var scroll_pos = 50; var scroll_time; if($('.gridcontainer').is(':visible'))  $('.gridcontainer').addclass('hidden');   $(window).scroll(function() {     cleartimeout(scroll_time);     var current_scroll = $(window).scrolltop();  if (current_scroll >= $('#topnav').outerheight()) {     if (current_scroll <= scroll_pos + 100) {         $('.gridcontainer').removeclass('hidden');         }     else {         $('.gridcontainer').addclass('hidden');       } }  scroll_time = settimeout(function() {     scroll_pos = $(window).scrolltop(); }, 600);

});
