STEP 12: Great! Our nested loop is finished. Let's start to customize and create our squares!

• Inside where you create your square, change the first parameter from 0 to x and the second from 0 to y.
• Then, change the third parameter from 100 to square_length - 5.
• Finally, change the square's color from "blue" to "white".
• Nice! Click Run to see our first square appear in the top righthand corner.
