The textbox and the text area does not expand when someone completes their information. It stays at a fixed width and height.
When entering information that exceeds the width of the textbox, the initial text on the textbox will scroll to the left to make room for the new information.
Meanwhile, the text area will scroll to the top when a user is entering their info. The user can manually expand this by dragging the bottom right corner of the text area.
