Here is a really simple classic calculator, is my attempt to practice JS and CSS, because I am being off of the FrontEnd environment for several years.
Like a classic calculator, the first part and kind of most difficult is the display segment.
To do it I am using a normal div, but with the ::before and ::after
There are a LOT of things to improve, just the code needs some documentation, maybe using a more modern approach.
I can use all of your opinions and suggestions.
Thanks for the reading.
