Why do you make the background image 200% 100%?
Not sure what that does exactly.

In this particular exercise, Guil uses 200% and 100% for the X and Y position of the background so he can position the neat-looking diamond shapes in a stance that emphasizes on the welcome text. If you set a negative value on each of the X and Y values, you will create a mirrored image of the current background.
I hope this is as simple as I thought it would be. If anyone got a different way of explaining this, You're welcome!

Hi, The percentage value of background-size property sets the width and height of the background image in percent of the parent element. first value= width second value= height.
