Prevent Mobile Safari from presenting toolbar when bottom of viewport is tapped

Question

We have a simple mobile app running in Mobile Safari (MS) on iOS. When the user scrolls down the page n pixels, a "top" button slides up from the bottom. The top button is fixed position. Problem is, when you start scrolling in MS, the navigation and toolbar UI is hidden. When you tap the "top" button, it reveals the bottom toolbar and a second tap is required to tap the "top" button. Is there any way to disable the default "tap on the bottom part of the viewport to reveal the toolbar" behavior so our top button works as expected (i.e. jumps to the top of the page with one click, not two?

Answer 1

No there is not. You can control the content of your webpage but not the behavior of the safari app.

Answer 2

The simple solution here is to add about 50px padding-bottom on your bottom most div. Safari seems to think that you are trying to access the bottom navigation bar, unless you click well above the bottom area. With extra padding at bottom, the user will click much higher on the page (not always, but in general).

Answer 3

Mika and typeoneerror are correct, but there is a workaround.

The best workaround solution I found (that doesn't require minimal-ui) is to force the bottom navigation of iOS Safari to always stay open/visible. That way, clicks to the bottom of the window never open the bottom navigation since it's always open.

To do that, you just need to apply some CSS and browser targeting with JS. Detailed steps on how:

• How might one force-show the mobile Safari bottom nav bar to show programmatically?
• Buttons aligned to bottom of page conflict with mobile Safari's menu bar
