Question

这是我的HTML和JQuery

我试图用jquery固定导航栏，并且即使没有jquery，固定的位置也不只是工作。无法弄清楚出了什么问题。我已经尝试了相关帖子中给出的建议，但似乎没有任何效果。我使用chrome浏览器检查了元素，当我向上滚动时，sticky类被添加到导航中，但不会使其粘在顶部。

还有我的CSS

<!DOCTYPE html>
<html>
<head>

    <link rel="stylesheet" type="text/css" href="stylesheet.css">
    <link rel="stylesheet" type="text/css" href="web-fonts-with-css/css/fontawesome-all.min.css">
    <script src="jquery.min.js"></script>
    <script type="text/javascript">
        $(window).scroll(function(){
            if($(this).scrollTop()>0){
                $('nav').addClass("sticky");
            }
            else
            {
                $('nav').removeClass("sticky");
            }
