Explanation:

This HTML document demonstrates how to specify the navigation behavior for arrow keys using CSS properties.
CSS comments are added to explain each section of the code.
Each button is styled individually using CSS.
Navigation properties such as nav-index, nav-right, nav-left, nav-down, and nav-up are used to define the navigation behavior when arrow keys are pressed.
The color property sets the color of the buttons.
