The first and simplest troubleshooting step is to ensure that an offset is specified using properties such as top, right, bottom, or left: .sticky-heading { position: sticky; top: 0; /* Offset not defined - sticky behavior won't activate */ } Without an offset, the sticky behavior won't activate. Additionally, ensure that the applied offset is appropriate for the intended scroll direction. For example, top or bottom for vertical scrolling, and left or right for horizontal scrolling.
The CodePen below demonstrates sticky elements inside grid containers: In the CodePen, the headings stick because the container holding each of them has enough scrollable space. To better visualize the layout, try adding borders around the content. This will help you see how each heading stays in place as you scroll through the sections.
Sticky elements can behave unexpectedly when placed inside containers with specific CSS properties. For instance, if the ancestor element has an overflow property, the sticky positioning may not work properly. Therefore, it's crucial to be aware of the CSS rules of the parent elements to ensure that the sticky behavior functions as intended.
