position: sticky is a positioning property in CSS that allows elements to remain in a specific position during scrolling. When an element is scrolled to a specified offset, it is "stickily positioned" and stays at that position until it is scrolled to another specified offset.

To use position: sticky, the following steps are required:

1. Add the position: sticky attribute to the element.

2. The specified element is positioned relative to its nearest ancestor element with a scroll box. You can use the top, right, bottom or left attributes to set the offset value.

For example, here is an example using position: sticky:

.container {
  height: 400px;
  overflow: auto;
}
.sticky-element {
  position: sticky;
  top: 20px;
  background-color: #f1f1f1;
  padding: 10px;
}

<div class="container">
  <div class="sticky-element">
    这是一个粘性元素
  </div>
  <!-- 其他内容 -->
</div>

In the above example, the .sticky-element element will stay when scrolling to a distance of 20px from the top of the .container element in that position.

Please note that the position: sticky attribute may not be supported in some older versions of browsers, so compatibility testing is required when using it.
