javascript - 如何将页眉区域粘贴在页面顶部？

Question

这是我模板的页眉区域部分。我想在顶部粘贴菜单栏和 Logo 。我在最多 4 天里尝试了很多。但我做不到。我使用 sticky.js 插件。但它不会发生。我的代码有什么问题？我无法理解。我在标题部分使用了视差。这就是问题所在。

.parallax-window {
  background: transparent;
}

.parallax_bg {
  z-index: 2;
  position: relative;
  color: #FFFFFF;
}

<div class="top_area parallax-window" data-z-index="1" data-parallax="scroll" data-image-src="img/header_img/header_background.jpg">
  <div class="parallax_bg">
    <div class="top_area">
