Issue

Symptom

The web page for this is based on the semantic-ui framework. Clearly we can see that the cursor for user input is not at the right position. The users will need to click done or exit the keyboard for avoiding this issue.

Cause

This problem is attributed to the fact that the position:fixed is not supported well on iOS Devices.

Solutions

easy fix: switch to absolute instead of fixed
