javascript - scrolltop() doesn't work with body.height() -


i've got fiddle. http://jsfiddle.net/qf47a/3/

well, tried similar code on website, worked great until added doctype. code return top 0px.

well take look: on jsfiddle. starts 0, , ascends negative numbers.

when add position:absolute; element in dom (in english) gives it's space float does. there isn't way around unless add height body.

basically body doesn't know #fly there body has no height.

if remove position:absolute; see

document.height work in case
