jQuery detect apple device css conditional -


i'm attempting detect whether user viewing website apple device, , if are, make div "carriage-promo" behave in way.

ordinarily div has transitions , animate take height 0px 40px when user scrolls down page, doesn't function on touch devices static.

consider:

    $(document).ready(function(){         var isiphone = navigator.useragent.tolowercase().indexof("iphone");         var isipad = navigator.useragent.tolowercase().indexof("ipad");         var isipod = navigator.useragent.tolowercase().indexof("ipod");          if(isiphone > -1)         {             $('#carriage-promo').css({'position':'fixed','bottom':'40px','width':'100%'});         }         if(isipad > -1)         {             $('#carriage-promo').css({'position':'fixed','bottom':'40px','width':'100%'});         }         if(isipod > -1)         {             $('#carriage-promo').css({'position':'fixed','bottom':'40px','width':'100%'});         }     });

i've ever used css3 media queries conditional styling behavior in past, occasion calls jquery/js.

any suggestions? i'm expecting either tiny syntax error, or have misunderstood how works!

try add line on ready:

window.scrollby(0, 1);

looks helps on ios > 5
way use position: absolute , set bottom position scrolltop + windowheight - promoheight
