Sticky Header

⚙️ Engineering & Technology By CampusDown Wiki Editorial Team Last updated
A sticky header is a top area that remains on screen as users scroll down, typically holding the logo, search and menu.

Why it follows

Without it, users scroll back up for search or menus; a sticky header removes that cost, keeping the next path close (Pirolli & Card, 1999). Laubheimer (2021) says it should be small, high-contrast and unobtrusive. Apps often shrink it on scroll like Material's top app bar (Google, n.d.).

The cost on small screens

Small screens show less (Kim et al., 2015), and headers eat reading space, especially in landscape. Many sites hide headers on scroll down and reveal them on a slight scroll up. The top is also far from thumbs (Fitts, 1954), so frequent actions may belong in bottom navigation.

Covered content and accessibility

position: sticky (MDN, n.d.) is easy, but anchor links often land headings under the header; scroll-padding-top fixes it. WCAG 2.2 (W3C, 2023) 2.4.11 forbids obscured focus, and 1.4.10 means zoomed headers must not fill the screen. Add safe area padding on notched devices.

FAQ

Are sticky headers always good?
They help on long pages needing frequent returns to key features; hide or shrink them on short or reading-focused screens.
How do sticky and fixed differ?
Sticky stays in flow until a threshold; fixed is pinned from the start and removed from flow.
