Sticky

Sticky Position in CSS allows an element to toggle between relative and fixed positioning based on the person’s scroll position. It commonly keeps certain elements, such as headers or navigation menus, in view when scrolling through content.

Syntax

position: sticky;

• The position: sticky property is often used with length or percentage values applied to top,right, bottom, or left to define the threshold for switching between relative and fixed positioning.

Note: To ensure position: sticky works, the containing block must have a defined height, and the sticky element should not be covered by other positioned elements.

Example

Make the .header element sticky so it remains visible at the top when scrolling past it.

.header {
  position: sticky;
  top: 0; /* Sticks to the top */
  background-color: white;
  padding: 10px;
  z-index: 1000; /* Ensure it's above other content */
}
