jQuery how to add another css in code? -

hi have code right on website...

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js" type="text/javascript" charset="utf-8"></script>  <script type="text/javascript" charset="utf-8">         var scrollspeed = 50;       // speed in milliseconds         var step = 1;               // how many pixels move per step         var current = 0;            // current pixel row         var imagewidth = 4000;      // background image width         var headerwidth = screen.width;     // how wide header is.          //the pixel row start new loop         var restartposition = -(imagewidth - headerwidth);          function scrollbg(){             //go next pixel row.             current -= step;              //if @ end of image, go top.             if (current == restartposition){                 current = 0;             }              //set css of header.             $('#body').css("background-position",current+"px 0");         }          //calls scrolling function repeatedly         var init = setinterval("scrollbg()", scrollspeed); </script>    

i'm trying add second jquery selector to:

$('#body').css("background-position",current+"px 0"); 

so css background-position property changed 2 elements.

ie 8 not work gradient , background i'm using nested div (class="flash-bg") background picture , want update it's background-position animate in ie well.

how can add "flash-bg" jquery code? there way add next '#body'? or repeat code except '#flash-bg'? thanks!

if want set background-position on both #body , .flash-bg, work:

$('#body, .flash-bg').css("background-position",current+"px 0"); 

also, in setinterval, can pass reference function instead of string eval:ed:

var init = setinterval(scrollbg, scrollspeed);
