Positioned through jQuery's aminate animation method.
An example is as follows:
scrollOffset($ ("#qa").offset());
// jQuery positions the scrollTop of the body equal to the top of pos to achieve scrolling
function scrollOffset(scroll_offset) {
$(" body,html").animate({
scrollTop: scroll_offset.top - 70
}, 0);
}
