Simple Drawing App

Hi, this is a pure html css application,
that I did few months ago,
Now I rediscovered it and I want to make it better,
if you have some good ideas…
ps. sorry, the code is terrible and unreadable,
I hope you enjoy it!
drawer;

If you have any question on how to use it please ask me,
but i think that’s really simple,(click and drag to move shapes)
