When smartphone users hold their devices using ONLY ONE HAND, the "Thumb Zone" is an area on the smartphone screen that your thumbs are able to easily reach and interact with a mobile menu. This area changes depending on these factors:
The size of your hand.
The size of your Smartphone screen.
Which thumbs you use to interact with a mobile navigation menu.
POSITION your website navigation menu at the bottom of your screen.
CENTER all navigation menu categories and web page links.
USE CSS Viewport Units Height to match the Optimal Thumb Area for your hand and smartphone screen. When you rotate the smartphone from portrait to landscape, the Menu Categories will shift automatically!
