Is it possible to bypass the navbar from the bottom of the mobile Safari?

Question

css

There is a task to press the button to the bottom of the screen.
But in mobile Safari, it turns out to be closed with a navbar, as in the screenshot.
What is the best way to proceed in this case?

Answer 1

why a photo, code is better, and code in the sandbox is even better. In general, pressing to the bottom is very simply achieved:

.myClass {
  position: fixed;
  right: 0;
  bottom: 0;
}

and html right before</body>

Answer 2

how do you press? pressed the block inside the bootstrap modal by adding

position: fixed;
    bottom: 0;
    left: 0;
    right: 0;

seemed to work normally
