Create a function
createCircle
: make it fire on every click on the page, and create adiv
at the position of the mouse on the screen, setting itsbackground
towhite
and its class tocircle
-
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 -
Create a function
setBox
which sets a box with the classbox
in the center of the page ; when a circle is inside that box, it has to be purple (use the CSS global variablevar(--purple)
asbackground
) ; once a circle enters the box, it is trapped inside and cannot go out of it anymore.
Hint: Be careful, a circle cannot overlap the box which has walls of
1px
, it has to be trapped strictly inside.
