Bottom Navigation Bar Overlapping Page Content in Bolt App
The fixed bottom navigation bar in your Bolt.new app covers the last items on every page. Users cannot see or tap buttons, form submit actions, and the last few items in lists are permanently hidden behind the nav bar. Scrolling to the bottom doesn't help because the nav bar moves with the viewport.
This is especially problematic on pages with action buttons at the bottom (checkout, submit, save), infinite scroll lists, and chat interfaces where the input field is at the bottom. Users literally cannot complete key actions because the navigation bar is covering them.
The problem gets worse on iPhones with the home indicator bar (iPhone X and later), where the safe area inset adds additional space that pushes the nav bar higher but doesn't account for the content behind it.
Error Messages You Might See
Common Causes
- Fixed bottom nav without content padding — The nav bar uses position: fixed but the page content doesn't have matching bottom padding to account for the nav height
- No safe area inset handling — On notched iPhones, the env(safe-area-inset-bottom) is not applied, causing the nav to overlap the home indicator area
- Dynamic content height changes — Content loads after the initial layout calculation, pushing elements behind the nav bar
- Z-index conflicts — The bottom nav has a lower z-index than some page elements, causing inconsistent overlap behavior
- Virtual keyboard pushing nav up — When the keyboard opens on mobile, the fixed bottom nav moves up and covers form inputs
How to Fix It
- Add bottom padding to main content — Add padding-bottom equal to your nav height plus safe area: <main className="pb-20"> for a nav bar that is h-16 (64px) with some buffer
- Handle safe area insets — Add env(safe-area-inset-bottom) to your nav: style={{ paddingBottom: 'env(safe-area-inset-bottom)' }} and add the viewport-fit=cover meta tag
- Hide nav when keyboard is open — Detect keyboard visibility and hide the bottom nav: use visualViewport.resize event to detect keyboard appearance
- Use a spacer element — Add an empty div with the same height as the nav bar at the end of your content: <div className="h-16" aria-hidden="true" />
- Set proper z-index — Give the bottom nav z-50 and ensure no other elements exceed it: <nav className="fixed bottom-0 inset-x-0 z-50 bg-white">
- Add viewport-fit meta tag — Update your viewport meta: <meta name="viewport" content="width=device-width, initial-scale=1, viewport-fit=cover" />

Get HelpFrequently Asked Questions
How do I calculate the right bottom padding for my content?
Measure your bottom nav height (usually 64px or h-16 in Tailwind) and add 16-20px buffer. In Tailwind, use pb-20 (80px) for a h-16 nav. On iOS, also add env(safe-area-inset-bottom) using the viewport-fit=cover meta tag.
Should I hide the bottom nav when the keyboard opens?
Yes, on mobile the keyboard pushes fixed bottom elements up, covering input fields. Detect keyboard visibility using the visualViewport API and hide or reposition the nav: window.visualViewport.addEventListener('resize', () => setKeyboardOpen(visualViewport.height < window.innerHeight * 0.75))
