The position: sticky CSS property combines the behaviors of position: relative and position: fixed, allowing an element to remain positioned within the viewport until it reaches a specified scroll position, after which it behaves like a relatively positioned element.

<div class="container">
  <div class="sticky-element">Sticky Element</div>
  <div class="content">
    <!-- Content goes here -->
  </div>
</div>

And

.sticky-element {
  position: sticky;
  top: 0;
  background-color: #f0f0f0;
}

Adding top: 0 to a position: sticky element ensures that it sticks to the top of its containing element, providing a fixed-like behavior until it reaches the top of its container.

Interaction with display: unset or overflow: auto

The display: unset property resets the display property to its inherited value, effectively removing any explicit display property set on the element, allowing position: sticky to function as intended.

.container {
  display: unset; /* Resetting display property */
  overflow: auto; /* Ensuring proper scrolling behavior */
}

CSS positioning, particularly position: sticky, empowers developers to create engaging and interactive web layouts. By understanding its interaction with properties like top: 0, display: unset, and overflow: auto, developers can leverage its full potential to craft seamless user experiences.

Experiment with position: sticky and its associated properties in your web projects, and unlock new possibilities for intuitive and dynamic webpage layouts.
