Password generator HTML/CSS/Javascript

What are you most proud of, and what would you do differently next time?

This is one of most challenging project I've ever done. Next time I will pay attention to css units, to use more rems then pixels etc.

What challenges did you encounter, and how did you overcome them?

The hardest challenge here was to generate password which contains all checked types of characters for sure. But I overcame that using some AI tools.

What specific areas of your project would you like help with?

I would like help with stylisation of slider thumb for Chrome please. I tried everything, including -webkit-appearance: none, appearance: none. But my CSS for this element in Chrome doesn't work.
