我正试图一个接一个地创建两个flexbox容器，我已经应用了许多类的组合来实现这一点。Flexbox被创建，但当我滚动时，下一个会低于上一个。输出如下所示：当前场景输出。
我的要求是这两个水平条是固定的，一个接一个，不管滚动。

<!--This div will be used in different html file and first div will be included using 'include' keyword of django. -->
<div class="d-flex flex-column flex-md-row align-items-center pt-5 px-md-4 border-bottom shadow-sm sticky-top" style="background-color: #80ccaa;"></div>

您可以像这样更改第二个水平条，并添加一些css：
<div class="d-flex flex-column flex-md-row align-items-center pt-5 px-md-4 border-bottom shadow-sm sticky-top" style="background-color: #80ccaa; position: fixed; width: 100%; margin-top: 50px"></div>
将想要的2个divs并排包裹在div内，使其成为flex
<body>
<div class="d-flex">
<div>...</div> // your first div
<div>...</div> // your second div
<div>
</body>
