Newsletter signup form with JS validation

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

This is the second time I finished this challenge and I wrote my JS way different this time, and added a new feature to it(automatic error state remover). So I suppose that I could redo this challenge every so often as my JS skills improve and all the time the solution would be different to a degree.

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

I faced different kind of challenges all that I would overcome by researching topics or watching videos. The biggest problem I faced and didn't manage to overcome was the fact that I wanted to store the current state of the html in a variable which sort of worked but it didn't store the CSS itself for some reason. But this is something I will do my best to learn for the next challenges that are coming up.

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

Just general code review for my JS code and how I styled the page with CSS. I still have a ton to learn from my mistakes.
