Mobile Safari does not support position: fixed when an input focused and virtual keyboard displayed.

To force it work the same way as Mobile Chrome, you have to use position: absolute, height: 100% for the whole page or a container for your pseudo-fixed elements, intercept scroll, touchend, focus, and blur events.

The trick is to put the tapped input control to the bottom of screen before it activates focus. In that case iOS Safari always scrolls viewport predictably and window.innerHeight becomes exactly visible height.

Open https://avesus.github.io/docs/ios-keep-fixed-on-input-focus.html in Mobile Safari to see how it works.

Please avoid forms where you have several focusable elements because more tricks to fix position will be necessary, those were added just for demonstration purposes.

The Ying-Yang of CEOs and Engineers

All successful startups begin with two founders. One guy is the Engineer, and the other guy is the business dude. Over the years of working with various people, I've learned what makes a good engineer, and what makes a good business dude, and the two are complete opposites of each other.
