Navbar en position: sticky

position sticky s'arrête prématurément

    Bonjour,

    Je suis entrain de coder un site à partir d'un model de base de dreamweaver.

    J'ai remplacé leur header par une navbar en position sticky, cela fonctionne très bien mais seulement sur une partie de la page.

    Pourtant sa div parente ( <div class="container" > contient bien l'ensemble du site..

    Je voudrais que la navbar reste bien "sticky" sur l'intégralité du site. 

    le code html : 

    <!doctype html>
<html lang="en-US">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
