Password generator using js vanilla

I had a lot of fun with this challenge. First, I realized the logic to generate a random password in javascript. Then I built the html. Then I design with css. By the way, I had some difficulties with the css to customize the checkboxes and the input range. That's why it doesn't look exactly like the template. Indeed, the use of -webkit-apparence-none to create its own input seems to me very tedious. So even with an input generator I did not manage to achieve the desired result.

The main logic of my javascript file is split in three parts: 1) Generates a password length, 2) Sets the length in the machine and 3) the machine creates a random password. To generate a random password I have three variables that contain the alphabet, numbers and special characters that I select randomly with math.floor and math .random. It works pretty well ! I think it's possible to refactor the code using regex Feel free to check my code!
