Answer 1

This is not react issue but a css one! This is how it works!

When you say height:100% it is calculated using parents height! If parent don't have a specific height browser cannot determine child's height in percentage!

On solution you can use is css3 vuewport unit, vh

div{ height:100vh; }

This will make your div to take 100 percent height of screen without changing any parent properties! Viewport unit wirk with respect to screen height, where 100vh = 100% screen height!

This is not a React issue. This is how css works. If a parent container does not have a specified height, you cannot use % to calculate the dimensions of a child element. You will need to explicitly set the height of the containers up to the body element.
