Create a sticky header with CSS
A sticky header stays pinned to the top of the viewport as the user scrolls, keeping navigation and branding always within reach. This generator produces the CSS using the position sticky property, with controls for the background colour, header height, an optional drop shadow that appears as content scrolls beneath it, and an optional frosted-glass blur for a modern translucent effect.
The sticky property is simpler and more performant than the older fixed-position approach, since it keeps the header in the normal document flow until scrolling.
Always-accessible navigation
Sticky headers improve usability on long pages by keeping the menu, search and logo visible, so users never have to scroll back to the top. A subtle shadow helps the header separate from the content beneath it, and the frosted blur lets background content show through faintly for a premium feel. Keep the header reasonably short so it does not consume too much screen space.
Ensure the header has a high enough z-index to stay above page content, which the generated CSS sets. All generation happens locally in your browser.
Notes on the generated code
Because the css sticky header generator runs entirely in your browser, you can experiment with every option and watch the generated code update instantly, with nothing uploaded and no account required. The output is clean, standards-based CSS that works in any project without external libraries or a build step, so you can paste it straight into your stylesheet and refine it further by hand whenever you need to.

Frequently Asked Questions
How does position sticky work?
The element scrolls normally until it reaches the specified offset from the top, then stays pinned there as the rest of the page scrolls.
Why use sticky instead of fixed?
Sticky keeps the header in the document flow until scrolling, which is simpler and avoids the overlap issues that fixed positioning can cause.
What does the frosted blur need?
It uses backdrop-filter, so it looks best when semi-transparent over content, letting the page show through faintly behind the header.
Why set a high z-index?
A high z-index keeps the sticky header above other page content as it scrolls underneath, which the generated CSS ensures.
