 ### Instructions
 
-Develop a trap to capture the elements when the mouse is getting too close to the center of the page!
+Develop a trap to capture the elements when the mouse is getting too close to the center of the page.
 
-- Create a function `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`
+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`.
 
-- Create a function `moveCircle`: make it fire when the mouse moves, and get the last circle created and makes it move along with the mouse
+- `moveCircle`: make it fire when the mouse moves, and get the last circle created and makes it move along with the mouse.
 
-- Create a function `setBox` which sets a box with the class `box` in the center of the page ; when a circle is inside that box, it has to be purple (use the CSS global variable `var(--purple)` as `background`) ; once a circle enters the box, it is trapped inside and cannot go out of it anymore.
+- `setBox`: which creates a box with the class `box` in the center of the page. When a circle is 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.
