 Develop a trap to capture the elements when the mouse is getting too close to the center of the page.
 
 Create the following functions:
+
 - `createCircle`: make it fire on every click on the page, and create a `div` at the position of the mouse on the screen, setting its `background` to `white` and its class to `circle`.
 
 - `moveCircle`: make it fire when the mouse moves, and get the last circle created and makes it move along with the mouse.
