CSS Sticky Header Snippet
Generate a practical position sticky header recipe.
A reliable sticky header
A header that sticks to the top on scroll is a common request and a surprisingly common source of bugs — z-index issues, jumpy offsets, background gaps. This generator produces a solid position: sticky header recipe you can trust.
Starting from a working snippet avoids the usual pitfalls. Set the offset and copy the CSS, then apply it to your header so it stays put as the page scrolls without the layout glitches that hand-rolled versions often introduce.
Copy-ready sticky header
position: sticky needs a top offset and an ancestor that does not clip overflow, which is the usual cause of a header that will not stick. Generated in your browser.
