Why Does My Sticky Element Stop Sticking in a Flexbox Container?

Sticky Element Gets Stuck When Using Flexbox

You've encountered an issue where a sticky element loses its stickiness when placed within a flexbox container. This occurs because flexbox elements inherently stretch to fill their available space, resulting in all elements sharing the same height and hindering vertical scrolling.

Fix: Adjust Alignment

To resolve this, add "align-self: flex-start" to the sticky element. This forces the element's height to be automatic rather than fixed, allowing the page to scroll as expected.

Browser Compatibility

While most browsers support this fix, Safari requires a "-webkit-" prefix for the sticky positioning. Additionally, sticky positioning may exhibit issues with tables in some browsers except Firefox.

Updated Code:

.flexbox-wrapper {
  display: flex;
  overflow: auto;
}

.sticky {
  position: -webkit-sticky;
  position: sticky;
  top: 0;
  align-self: flex-start;
  background-color: red;
}
