Way to make sticky navigation bar work inside other components?

Question

I have the following structure in my project:

<app-nav-bar></app-nav-bar>
    <app-slider></app-slider>
    <app-solution></app-solution>
    <app-platform></app-platform>
    <app-team></app-team>
    <app-contact></app-contact>
    <app-footer></app-footer>

The sticky navigation bar is not working as it only works within its component, how to make it work within the component and keep it on top.

I tried putting it in app.component.html but it doesn't work.

HTML arranges application components in a container, including app-nav-bar on top, followed by other components. Padding provides space for a sticky navigation bar. CSS styles app-nav-bar to make it sticky on top, with background color, white text and padding. It stays fixed while scrolling due to position: sticky;.

/* 应用基本样式以确保导航栏占用空间 */
.app-container {
  position: relative;
  padding-top: 60px; /* 根据导航栏的高度调整此值 */
}

/* 粘性导航栏的样式 */
app-nav-bar {
  position: sticky;
  top: 0;
  background-color: #333;
  color: white;
  padding: 10px 0;
  text-align: center;
  z-index: 100; /* 确保导航栏在其他内容之上 */
}

/* 其余组件的样式 */
