Pinning a jquery region?

Question

JavaScript

Good time of the day.
Can you tell me which jquery plugin implements the effect like here www.now.ru?
The main menu will scroll along with the entire page, but not immediately, but until the top advertising banner is hidden.
Thanks in advance.

Answer 1

I'm a bike lover:
$(document).onscroll( function(){
if( scroll position > 50px )
{
$( "#go_block" ).css({ 'position': "static" })
}
otherwise
{
$( " #id_block" ).css({ 'position': "inherited" })
}
} )
