****## Mouse trap

Instructions

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.

• setBox: which creates a box with the class box in the center of the page. When a circle is entirely inside that box, it has to be purple (use the CSS global variable var(--purple) as its background). Once a circle enters the box, it is trapped inside and cannot escape.

Hint: Be careful, a circle cannot overlap the box which has walls of 1px. It has to be trapped strictly inside.
