# Keep focused elements unobscured
A visible focus ring is not enough if the focused element sits behind a sticky header or footer. Keyboard users need to see the actual focused control and the focus indicator at the same time in order to continue the task.
## Quick Reference
- Sticky UI must not cover the focused control while keyboard users tab through the page
- Use `scroll-padding` or equivalent spacing when fixed headers or footers are present
- Test with cookie banners, chat widgets, and consent bars open
- Re-test at zoomed and mobile layouts where overlap problems usually appear
## Check
Audit keyboard focus with all sticky UI active. Check headers, footers, cookie banners, promo bars, and chat launchers for cases where the focused element scrolls underneath them.
